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?

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.
What happens when light goes from a less dense medium to a more dense medium?
When light goes from a less dense to a more dense medium, it slows down and changes direction. This change in speed and direction is known as refraction. Refraction occurs because the speed of light is different in different mediums, causing the light waves to bend as they enter the more dense medium.
When waves enter a more dense medium they bend away or toward normal?
When waves enter a more dense medium, they tend to bend toward the normal, or the line perpendicular to the interface. This phenomenon is known as refraction and occurs because the speed of the wave changes as it moves from one medium to another, causing it to change direction.
A change in speed of a wave as it enter a new medium produced a change in?
The change in speed of a wave as it enters a new medium results in a change in its wavelength and possibly its direction. This phenomenon is known as refraction, which occurs due to the difference in the speed of the wave in the two different mediums.
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)
Why does wavelength o light decrease when enter to denser medium?
When light enters a denser medium, its speed decreases due to interactions with the medium's particles. This change in speed causes the frequency of the light to remain constant but the wavelength to decrease, following the equation v = fλ, where v is the speed of light, f is the frequency, and λ is the wavelength.
What is the name of the effect where light rays are bent as they enter a medium with a different density?
The name of the effect is refraction. It occurs when light rays pass from one medium to another with a different density, causing the rays to change direction.
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.
Does the transform ability trigger an enter the battlefield effect?
No, the transform ability does not trigger an enter the battlefield effect.
Why frequency does not change when enter from one medium to another?
Frequency means how often the waves pass per second. If, for example, 1000 wave cycles (wave crests) are emitted per second, you would expect the 1000 wave crests to pass any point - unless there are some special effects, such as the Doppler effect, when either the emitter or the recipient moves.
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.
How does a decrease in velocity affect the frequency and wavelength of the waves entering the shallow water?
A decrease in velocity of the waves will cause a decrease in frequency and a decrease in wavelength as the waves enter shallow water. This is due to the relationship between velocity, frequency, and wavelength which is defined by the equation: velocity = frequency x wavelength.
What kind of meduim does not permit light rays to enter?
An opaque medium.
