Does the wavelength and frequency of light changes when it enters glass from air?

Nothing. The speed changes. We live in a universe where electromagnetic waves change frequency if they can't change speed (and in a vacuum they can't), and only change speed if they enter another medium like glass.

The frequency is determined by the source, and it doesn't change.
However, since the speed is different in different media, the wavelength
changes. In passing from air into glass, the speed of light decreases, and
wavelengths therefore increase.

When a ray of light from air enters to glass what happens to wavelength?
It will not change. Glass slows light but does not change it frequency.
Does thr color of light depends upon its wavelength or frequency fundamentally?
Fundamentally it is the frequency. When light travels into a medium like glass the speed and wavelength can decrease but the frequency and color do not change. If light does not pass thru different mediums then it is safe to talk about its color in terms of either frequency or wavelength (one is inversely proportional to the other by speed of light = frequency x wavelength) but fundamentally one would use frequency.
Does a light ray bend if it enters a glass block perpendicularly?
No, a light ray does not bend if it enters a glass block perpendicularly.
Which color of visible light travels the slowest through a glass prism?
The lowest frequency / longest wavelength of visible light are those of the last color you can see on the RED end of the rainbow.
How could you find the sound frequency to break a glass?
High frequency sound waves can shatter glass if powerful enough. This happens because the glass vibrates at the same frequency as the sound waves on the outer surface of the glass, but at lower frequencies inside the glass. This causes interference in the waveforms moving through the glass, which stress the glass, causing it to break. This is a different effect than when a single sharp sound, such as an explosion, pushes the glass beyond its breaking point.
When a ray of light from air enters to glass what happens to wavelength?
It will not change. Glass slows light but does not change it frequency.
What happens to the wavelength of light when a ray of light enters a glass slab from air?
when the light enters into another medium, its speed changes. Hence there will be the change in the wavelength. Speed = frequency times wavelength Since the speed of light is less is glass compare to the air, its wave length will be less in glass.
What type of relationship exists between wavelength and frequency?
the product of wavelength and frequency is speed of propagation for a vacuum about 300,000 km/s, about the same in air, less for glass or water

What is the velocity change when the ray of light passes from air to glass?
When a photon goes say from air to water, it slows down according to; n=c/v where n is refractive index of water c is velocity of light in air v is velocity of light in water It is stated that the frequency of the photon doesn't change when the photon enters the water. Only the wavelength changes.
What occurs when light passes from water into a flint glass?
Its speed decreases, its wavelength becomes smaller, and its frequency remains the same.
Can a glass prism separate white into different colors?
Yes. The reason this works is because the index of refraction varies depending on the frequency (or wavelength) of the light.
Which characteristic of a light wave must increase as the light wave passes from glass into air?
The speed. Therefore, the wavelength also increases, since the frequency stays the same.
What color in the visable spectrum is bent the least?
Red bends the least. If you look at a prism with a beam of light shining through it, you will see violet is bent the most. This due to the refractive index of the glass changing the wavelength. Velocity & frequency are components of wavelength. So the refractive index is a ratio by which the speed of light is changed. I am not sure if frequency is changed.
Does a light ray bend if it enters a glass block perpendicularly?
No, a light ray does not bend if it enters a glass block perpendicularly.
Which light wavelength make it through glass faster?
Red light (longer wavelength)
How are speeds of electromagnetic radiation frequency and wave length related?
The speed of electromagnetic radiation (light) in a vacuum is a constant, independent of frequency or wavelength. However in a medium (e.g. glass, water, air, diamond) it is no longer a constant, allowing the colors to be separated into a spectrum.
