A thin square-wave phase grating has a thickness that varies with period A such that the phase of the transmitted light jumps between O ând ф radians. Find an expression for the diffraction efficiency of this grating for the first diffraction orders What value of ф produces the maximum diffraction efficiency?

Answers

Answer 1

The diffraction efficiency of a thin square-wave phase grating for the first diffraction orders can be calculated using the following expression:

η = (sin(Nδ/2)/Nsin(δ/2))^2

where η is the diffraction efficiency, N is the number of grating periods, and δ is the phase shift of the transmitted light.

In this case, the phase shift varies between 0 and ф radians, so we can write:

δ = ф/N

Plugging this into the previous equation, we get:

η = (sin(Nф/2)/Nsin(ф/2))^2

To find the value of ф that produces the maximum diffraction efficiency, we can take the derivative of η with respect to ф and set it equal to zero:

dη/dф = 0

After some algebraic manipulation, we get:

sin(Nф) = Nsin(ф)

This equation has multiple solutions, but the one that produces the maximum diffraction efficiency is given by:

ф = arcsin(1/N)

Substituting this value of ф back into the expression for η, we get:

ηmax = (sin(π/2N))^2

Therefore, the maximum diffraction efficiency of the grating occurs when the phase shift is equal to the arcsin of 1/N, and it is given by the square of the sine of half the period of the grating.

To find an expression for the diffraction efficiency of a thin square-wave phase grating with thickness varying with period A, and the phase of transmitted light jumping between 0 and ф radians, we can use the following formula:

Diffraction Efficiency (η) = (sin²(ф/2))/(ф/2)²

To find the value of ф that produces the maximum diffraction efficiency, we need to look for the maximum value of the function η. The maximum diffraction efficiency occurs when ф = π, which gives:

η_max = (sin²(π/2))/(π/2)² = 1

So, the maximum diffraction efficiency for the first diffraction orders of the grating is achieved when ф = π radians.

What is the power (in Watts) of a bus that uses 35 N of force to move 20 m in 5s?

Answers

Power is the rate at which work is done, and it is measured in watts (W). It can be calculated using the formula:

Power = Work / Time

Work can be calculated using the formula:

Work = Force x Distance x cos(theta)

where Force is measured in Newtons, Distance is measured in meters and theta is the angle between the force and displacement vectors.

As we are not giving any value for the angle between force and displacement vectors, we can assume it's zero degree, so the cos(0)=1

So we can plug in the given values to find the work done:

Work = 35 N x 20 m x 1 = 700 J

Now we can calculate power:

Power = 700 J / 5 s = 140 W

Therefore, the power of the bus is 140 Watts

Analyze the IR spectra for both t-butanol and 1-butanol.

If the reactions were successful what do you expect to see in the IR of the product compared to the starting material?

Answers

If the reactions were successful then we can see the reactions involved O-H groups of the alcohols then the O-H stretching will not be observed in the product.

Analysis of IR spectrum of 1-butanol:

There are sp3 C-H stretching and CH2 bending modes at 2900 and 1500 cm-1 and there is a C-O stretching mode near 1050 cm-1. There is a very large peak around 3400 cm-1. O-H peaks are usually very broad due to H -bonding.The rounded shape  O-H stretching modes occurs because of hydrogen bonding between different hydroxy groups.

Because protons are shared to varying extent with neighboring oxygens, the covalent O-H bonds in alcohol all vibrate at slightly different frequencies and show up at slightly different positions in the IR spectrum.

Instead of seeing one sharp peak, the entire range is observed as a whole lot of them merged into one broad peak. Since C-H bonds don't hydrogen bond very well, hence this phenomenon is not observed for C-H stretching.

Analysis of IR spectrum of tertiary-butyl alcohol:

There are sp3 C-H stretching and alkane C-H bending modes at 2900 and 1500 cm-1 and there is a strong C-O stretching mode near 1200 cm-1 indicative of tertiary C-O, there is a broad peak around 3400 cm-1 indicative of H bonding.

Answers

If the boy swings the toy with a linear velocity of 2m/s, the toy will move in a circle. The force required to maintain the toy's motion IS 750g * m/s^2

The linear velocity of an object moving in a circle is related to its angular velocity (measured in radians per second) and the radius of the circle. The linear velocity is given by the equation: v = r * w, where v is the linear velocity, r is the radius of the circle, and w is the angular velocity.

In this case, the radius of the circle is 0.8m and the linear velocity is 2m/s. Therefore, the angular velocity of the toy can be calculated as: w = v/r = 2m/s / 0.8m = 2.5 rad/s.

The toy has a mass of 150g and it moves in a vertical circle with a radius of 0.8m and a linear velocity of 2m/s, so it will move in a circle. The force required to maintain this motion is the centripetal force, which is given by the equation F = m * a, where F is the force, m is the mass of the toy and a is the centripetal acceleration. The centripetal acceleration is given by the equation a = v^2/r, where v is the linear velocity and r is the radius of the circle.

So, the force required to maintain the toy's motion is F = m * a = 150g * (2m/s)^2 / 0.8m = 750g * m/s^2

The efficiency of the engine is given 27.5%. The input energy of 2.5 L gasoline is 83.75 J. Then, the energy output will be 23.01 J.

What is engine efficiency ?

The efficiency of an engine is the ratio of its output work done to the energy input. No engine can have 100% efficiency. Hence, some energy is lost in the form of heat.

Given that, the efficiency of the car's engine is 27.5 %. Input energy of 1 L gasoline is 33.5 J. Then, energy input for 2.5 l is:

input energy = 2.5  × 33.5 = 83.75 J.

Engine efficiency = energy output/ input energy × 100

O/ 83.75J × 100 = 27.5 %

O/83.75 = 0.275

then output energy = 83.75 × 0.275 = 23.01 J.

a) By drawing a free body diagram, we represent the two types of forces on the seat. They are represented by the equation, sum of forces in the y direction,

∑F = ma

T cos θ − mg = 0

T = mg / cos θ

Sum of forces in the centripetal direction,

(mg / cos θ) sin θ = m v² / r

m g tan θ = m v² / r

g tan θ = v² / r

v = √(gr tan θ)

First, let us find the radius of the path,

r = 7.4 / 2 + 1.81 sin 26.6°

r =  3.7 + 1.81× 0.45 = 6.33 m

Question 6(Multiple Choice Worth 3 points)(04.01 MC)Starting with the European settlers, humans have introduced earthworms from Europe and Asia into North American forests. These introductions continue through the transport of soil that contains non-native earthworms, such as during construction and through the release of non-native earthworms used for fishing. The effects of non-native earthworms are especially large in forests that did not have any native earthworms. For example, forests of the Great Lakes region did not previously have earthworms until humans introduced them. When non-native earthworms are introduced, the thick layer of leaves, known as leaf litter, covering the ground disappears quickly, thereby altering biogeochemical cycles.What is a possible beneficial consequence of introducing the earthworms to forests in the Great Lake regions? The earthworm increases the energy flow from one tropic level to the next. The earthworms provide competition for other native, primary consumers. The earthworms burrow, which improves the nutrients, flow of air, and water underground. The earthworms are secondary consumers that provide another food source for tertiary consumers. eeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeere
