The speed of light IN A VACUUM is always the same. In substances other than the vacuum, the speed of light is usually slower than in a vacuum.

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.


Which property of light ray does not change in refraction?

The frequency of a light ray does not change when it undergoes refraction. The wavelength and speed of light can change, but the frequency remains constant. This is because frequency is a characteristic of the light source, not of the medium through which light is traveling.


Why wavelenth changes with speed of light?

Wavelength does not change with the speed of light, nor does the speed of light change for different wave lengths. Wavelength x frequency = c (the speed of light) always for any given medium through which it travels. Greater wavelength yields lower frequency, so the speed is always the same. Speed changes as light passes into different media transparent to light, but the change in speed has nothing to do with any change in frequency or wavelength. Those are related only to the nature of the material and the particular light energies it may pass or absorb. So white light passing through a red filter emerges red because the blue and green frequencies have been absorbed by the filtering material. That change in wavelength and frequency is not related to any change in speed within the filter.


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.


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.

What happens to the frequency of light as it goes from air to water?

The frequency of light remains constant as it changes medium from air to water. However, the speed and wavelength of light will change, causing it to bend or refract.

What happens to frequency when a ray of light passes from air to water?

The frequency of light remains constant when passing from air to water. However, the speed of light changes due to the change in the medium, causing the wavelength to change. This change in wavelength results in the light bending or refracting at the interface between air and water.

Why frequency does not change when light travels from one media to other?

When light travels from one media to another, its frequency remains the same because frequency is a fundamental property of the light wave itself and is determined by the source of the light. The speed and wavelength of light may change as it enters a new medium, but the frequency remains constant. This is described by the equation: frequency = speed of light / wavelength.


What is the relationship between the wavelength, frequency, and the speed of light in different media?

The relationship between wavelength, frequency, and the speed of light in different media is described by the equation: speed of light wavelength x frequency. In different media, the speed of light remains constant, but the wavelength and frequency may change. When light travels through different media, such as air, water, or glass, its wavelength and frequency can be altered, while the speed of light remains constant.


When light wave change its medium from dense to rare frequency increases or decreases?

When a light wave enters a medium where the speed of light is slower (from dense to rare medium), the frequency remains the same but the wavelength decreases. This is because the speed of light is inversely proportional to the wavelength.


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.


How could you find the wavelength of light if you knew its speed and frequency?

You can use the equation: wavelength = speed of light / frequency. Given the speed of light (3.00 x 10^8 m/s) and the frequency of the light source, divide the speed of light by the frequency to determine the wavelength of the light.

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.


Why does wavelength change during refraction?

Wavelength changes during refraction because the speed of light changes when it passes through different mediums, causing the frequency to remain constant. According to the equation c = fλ (where c is the speed of light, f is the frequency, and λ is the wavelength), when the speed of light changes, the wavelength must also change to keep the frequency constant.
