If light is invisible ,how does the surrounding area
become visible​

Answer:

Reflection, absorption and re-emission.

To clarify, you mentioned light is not visible. Of course that is not true, we can see light. our retinas are sensitive to light within a certain range of frequencies. you may be commenting on the fact that if there is a beam of light in front of me traveling from right to left, I won’t see it. That’s true. If it were a ball I would see it. That is because light strikes the ball, is reflected, absorbed, and re-emitted or some combination of the above, then that light strikes my eye.

As a side note, if the ball were somehow changed by the light which struck it (change of course due to momentum of light impact) then I may not be able to trust that the image I see truly represents the current condition of the ball. But for most balls we can see, this is not the case. If, however, we do go smaller in our attempt to ‘see’ light, we won’t necessarily be able to trust our instinctive intuition. That is informed by the large scale world we observe with our unaided eye. We would have to learn to trust our observations however those observations come. And the observed truth of the very small, the world of quantum physics, is rather different than our unaided perception. It is nevertheless equally valid.

Back to the main point.

If you like to play the semantics game of asking whether you see the ball or see the light, suit yourself. The ball interacts with light, the light interacts with my eye, my eye sends data to my brain for interpretation. I’m fine with either version of ‘seeing’ the ball or ‘seeing’ the light.

Here’s an example to hopefully clarify.

I’m outside on a sunny day, no electric lights around, only sunlight. We all know sunlight is well collimated, one-directional. I’m in my back yard in the shade of my awning. No direct sunlight strikes me or the ball in my hand.

How do I see the ball in my hand?

Direct sunlight strikes a number of objects around me, the ground, my pool, etc. I don’t see any of that light. All of those objects reflect some light. That reflected light leaves the objects at certain limited angles based on the angle of incidence of the sunlight striking that surface. They also absorb some light. They then re-emit the light they absorb. Based on the surface characteristics, this re-emitted light shoots out in all directions away from the surface. They all become sources of multi-directional light nearby, just much lower intensity. Like a bunch of little light bulbs. So the ball I hold (in the awning’s shadow) is lit from a number of sources, just much more dimly than the ground lit by direct sunlight. And so the ball appears darker. It is in the shadow after all.

By the same principle, if the part of Earth you are standing on is in the shadow of the rest of the Earth, i.e. it is nighttime, then you won’t see anything. Unless of course there are other objects around Earth (moon, et al.) that absorb and re-emit light. When the sun, Earth, and moon are lined up so that the sunny side of the moon has a lot of its surface area facing towards Earth (full moon) then there is a lot of reflected and re-emited light striking Earth. Those are nights when it is easier to see by moonlight, which is of course sunlight.

How does Scrooge react/ respond upon seeing the Ghost of Yet to Come? What words/ phrases in the text convey these feelings? ps i need a paragraph just 5 sentences using race

Plllzzz What is the theme of the poem
I was thrown Through the hard cold steel waves like a child lost in an unending sea
Waves of anger because of the unknown waves capped with winter frost were unyielding and severe
Shivering the waves consumed me fear shone through my eyes and my now bluish skin felt clammy to the touch
Fear held me anchored for I knew not how to raise my head above the flashing flint of the ocean
Where was the ocean i loves the Venetian blue the gentle lulling the conformity that I knew
A beast that I know not how to control was now living and consuming me
Why was I being forsaken I needed sanctuary I silently pleaded to an unyielding sea of storming iron
I have more to live anger won’t overcome me again please I have more to give

Read this excerpt from Exploring the Titanic.

Alvin could only dive to 6,000 feet. Since the average depth of the deep ocean is about 12,000 feet, the Navy decided to give it a new hull of titanium alloy, a very strong metal that could hold up to huge underwater pressures and allow us to dive to 13,000 feet. By chance, this refitting project was called Project Titanus.

Titanium, Titanus, Titanic – that started me thinking. The Titanic was thought to lie at a depth of just over 12,000 feet.

Based on the excerpt, why does the author include the name of the refitting project?

to explain how Alvin was similar to the Titanic
to show how titanium was found inside the Titanic
to connect Alvin with the author’s search for the Titanic
to describe how Project Titanus was named after the Titanic

FIND ANALOGIES IN THE POEM

"Wandering As A Clouds"

Our lives are but clouds wandering across a sky

Restlessly drifting along with a tempestuous wind

Sometimes billowing puffed up sometimes thinned

Or grey with darkened streaks of lightning flashing by

They speed with no mercy in the jet

stream high above

Or labouring they shed their heavy load upon the soil With cymbals' of crashing thunder

they bubble and boil

Yet with ageless beauty they're looked on with love

Like clouds our lives are full of wandering thoughts

Those times we feel happy or pain or

laugh or we weep

We play and we work and make

appointments we can't keep

Of winning the lottery a cheque ending one and six noughts

And have dreams of wielding power

prestige or of love

But spare a thought for those with

monotonous dread

We all drift through this mortal life

until we are dead

And live in memories and history that

once we were part of

We are those wandering clouds in the

heat of the day

We start out as nothing just a few

gentle wisps that grow Shaped by the wheel of fortune

takes a throw

as fate

Then when our cloud evaporates we simply fade away​
