What happens to the intensity of light when it enters a dnser medium?
There's no reason to expect that the intensity of light must necessarily change when it enters a different medium.
What is the speed of light in oil?
Einstein says that the speed of light is the same to all observers. This raises some interesting problems and his theories of relativity set out to solve them. But that aside, the speed of light is the same in olive oil and a diamond as it is anywhere else.
Why light bends towards normal when it enters from optically rare to optically denser medium why it does not bend away from the normal?
This is because of the speed of light getting reduced as it enters into the denser medium. Think of the FRONT of the wave as it enters a more-dense medium at an angle, and its speed decreases. Vizualize it in very slow motion: -- The wave-front arrives at angle, so part of it is across the boundary and into the new medium, while part of it is still out in the old medium. -- The part of the wave-front in the new medium is traveling slower, while the part that hasn't quite reached the boundary yet is still out in the old medium and traveling faster. -- If your vizualization is running accurately, this action is causing the whole wave-front to turn, becoming more parallel with the boundary, and its direction of motion turning toward the normal.
What happens to the speed of light as light travels though materials?
The speed of light is not affected by the density of the medium. Its the path of the light that is affected . Phenomenon like reflection or refraction take place when the light goes to different medium
Why frequency of light never change when light changes medium?
When light enters another medium it changes speed, but thewavelength changes correspondingly so that the frequency does not change. For example, if light enters a medium where its speed is cut in half, then the wavelength will also be reduced by half.
What happens to the intensity of light when it enters a dnser medium?
There's no reason to expect that the intensity of light must necessarily change when it enters a different medium.
What is effect on wavelength of light when it enter dense medium?
When light enters a denser medium than it was previously travelling in, the wavelength gets shorter because the speed of the light slows down: v=w/f where v is the velocity of a wave, w is the wave length, and f is the frequency. When light enters the new medium, f does not change but v decreases so w also decreases. Actually, the density of the medium is not accurate. The medium is not denser it just is "optically denser" which means it has a higher index of refraction. It has nothing to do with actual density, which is weight divided by volume.
When the light enters a denser medium what happens to the wavelengths?
The denser an object is, the slower a wave will travel through it because the wave will interact (collide!) with more molecules. Each collision will serve to slow down the wave of light. Therefore, the wavelength will increase, becoming longer.
Is there any phase change occurred when sound wave refracted from denser medium to a rarer medium?
NO
Why frequency of light is not change When it enter from a rarer medium to denser medium?
Frequency is a function of the energy level of the photon. Changing the medium does not change that energy level.
What happens to the wavelength of electromagnetic waves as they travel through a denser medium?
The waves become smaller.
What happens as light enters a medium and its speed increases?
It reflects a rainbow pattern
Why does velocity of light in rarer medium than in denser medium?
Light travels from a denser medium to a rarer medium because you did not close your curtains. It then passed through the denser window glass into the rarer air outside. The people outside the house saw you running your finger around the bottom of the cake getting a little of the icing.
What is the change of direction when a wave enters a different medium called?
Refraction
Is it necessary to have a denser medium for the reflection of light?
no. if the medium is denser, the reflection of light would not do it.
What happens to the speed of a wave when it travels through a denser medium and apply this to the layers of the earth?
the same thing that happens when you divide by zero.
When light enters a different medium the amount that the light is bent as it enters the medium is determined by the medium's index of .?
When light enters a different medium, the amount that the light is bent as it enters the medium is determined by the medium's index of..........=refraction
