This one is impossible, sooo confusing!?

Question

Pretend a person can walk only at a certain pace -- no faster, no slower. If you time her uninterrupted walk across a room of known length, you can calculate her walking speed. If, however, she stops momentarily along the way to greet others in the room, the extra time spent in her brief interactions gives an average speed across the room that is less than her walking speed. How is this like light passing through glass? In what way is it not?

Answer 1

The speed of light is constant in a vacuum only. When light passess through objects, it's speed is reduced.

It's different than the girl scenario because the light doesn't actually stop, it's simply slowing down. The girl is stopping.

Answer 2

Well, I'm no scientist but here's a guess;

She passes through open space at the same speed each time.
Light travels through open space at the same speed each time.

When she travels through a room full of people, she stops and mingles with different people, so her path is NOT in a straight line, nor is it in an open space. She spreads her self out to interact with different people.

When light travels through water, it's not traveling through empty space any longer. It also spreads itself out to interact with facets of the prism the water creates. It's colors are broken apart so that it's path is now in many different directions.

The differences; when she interacts with people, she is still the same entity she was, and has the same appearance. Light is still light, but it's broken up into red, orange, yellow, green, blue, indigo and violet, so it comes out on the other side of the room (glass) with a different appearance than it had when it entered the glass.

Answer 3

I think that what the question is referring to is that light appears to slow down as it passes through glass. Light can only travel at 186K miles / sec. No more and no less. When it passes through glass the photons are absorbed and remitted by the electrons in the glass. The time that this takes makes makes it appear to be moving slower through the glass then it actually is.

Answer 4

Its like light because light's speen is constant, but when it is going through glass it is hitting the atoms inside the glass so it takes more time to get "outside of the glass" because it is traveling a slightly further distance because it isnt going in a straight line. It isnt like the senerio because light is constantly moving.

Answer 5

are u like some professor or something?

wtf??!?
omg sorry!
i dont know!!!!!
haha
