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.

What is the passage of an EM wave through a medium?
when EM waves encounter a material medium, they can interact with it in much the same way that mechanical waves do. A mechanical wave transfer energy in two ways. As it travels, the wave moves potential energy from one place to another.
What causes light rays to bend when they enter a new medium at an angle?
Light rays bend when they enter a new medium at an angle because they either slow down or speed up. They speed up the most if they are in a vacuum.
What happens when a light wave does not bounce off of an object?
Three situations may arise when a light wave travelling from an optical medium to another optical medium strikes the second medium. They are as follows: 1. The light ray may bounce off of the medium to which it was travelling with a change in angle.This phenomenon is also known as reflection of light. 2. The light ray may pass through the second medium with a deviation in its angle of incidence. This is also known as refraction of light. 3. The ray may be absorbed by the second medium. If a light wave does not bounce off of an object then either 1. or 2. may happen. That light ray enter the second medium, or it may be absorbed by that medium.
What happens to the frequency and wave lengths as waves enter shallow water?
describes the effect of water waves passing into shallow water?
What is the difference between MLA 7th Edition and MLA 9th Edition besides the fact that you dont have to enter the web address on web sources?
Now you have to specify the medium of the information, such as Web, Print, or PDF File.
A change in speed of a wave as it enter a new medium produced a change in?
wavelength
What is the name of the effect where light rays are bent as they enter a medium with a different density?
Refraction
Why does wavelength o light decrease when enter to denser medium?
That is because the light's SPEED decreases. Also, because the frequency doesn't change. As a reminder, the wavelength is equal to the speed of the wave, divided by the frequency.
How or why does light enter water by a limited distance?
Light enter the water base on the principle of refraction of wave,during this process light moves from a denser medium to a less denser medium leading to the change in wavelength of the light That, however true, is not an answer to the question. (VanZanten)

What causes light rays to bend when they enter a new medium in a new angle?
when light rays enter a new medium in a new angle it may speed up or speed down
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.
When light rays enter a medium at an angle they?
The light rays will refract towards the normal of the medium and emerge out at the same angle.
What kind of meduim does not permit light rays to enter?
An opaque medium.
The bending of waves as they enter a different medium?
That's called "refraction".
Why do you use soap in the shower?
Water alone cannot enter your pores because it isn't dense enough to go inside and clean your pores. Soap is used to make water dense enough to enter the pores and clean them, making you a lot more cleaner.
How does ram air effect a automotive engine?
It allows cooler, more dense air to enter the engine. Cooler, more dense air adds greatly to the efficiency of the combustion process inside the engine, providing more engine power output. Ram Air is similar to adding a hood scoop or aftermarket intake kit to a non-Ram-Air engine
