Question

Please help me with these!!!! ANYONE???????????????????

1)What causes light to refract as it passes through different media?

2)How does the frequency and the energy change as you move from radio to gamma waves?

I appreciate any explanation and will gve medals. Thanks :)

Answer 1

help?

Answer 2

Its velocity changes and light bends if hits interface at an angle.

Two important equations

E = h f, energy = Planck's constant x frequency

radio waves have much lower frequencies than do gamma rays.

Answer 3

Bending of Light can be considered as a consequence of it's (light's) attempt to cover the (complete) distance in the shortest amount of time possible.

Answer 4

whats actually the necessity for completing the path in shortest ?

Answer 5

^^ Please rephrase the sentence.

Answer 6

why does light want to cover the distance in shortest amount of time??

Answer 7

The bending of light can be explained via wave optics without using this ^^ constraint.

Still considering it from the point of view of ray optics; it is a very good question. For now, I'll just say that for every other value of time (except the shortest time) there will be two possible paths.

I'll need some time to find a satisfying answer.
