Frequency doesn't change in the transition between media. Speed changes, with a consequent change
in wavelength. In passing to a less-dense medium, speed and wavelength both increase.

No. It's speed and wavelength may change, but not its frequency.

Which parameter of light doesnt change on reflection?

Frequency is the parameter of light which doesnt change on reflection because it is the ratio of velocity of light in medium and wavelength of the particle.Hence,when velocity increases wavelength also increases and when velocity decreases wavelength also decreases but its ratio always remains constant.


How do you convert short wave to medium wave?

Sound . . .direct the sound into a less-dense medium. Its frequency remains constant butits speed decreases, so its wavelength increases.Light . . .direct the light into a medium with a higher refractive index. Its frequency remainsconstant but its speed decreases, so its wavelength increases.


If the frequency of an electromagnetic wave increases the speed of the wave does what?

If the frequency increases, the wavelength decreases. Wavelength lambda and frequency f are connected by the speed cof the medium. c can be air = 343 m/s at 20 degrees celsius or water at 0 dgrees = 1450 m/s. c can be light waves or electromagnetic waves = 299 792 458 m/s. The formulas are: c = lambda x f f = c / lambda lambda = c / f


As the speed of a particle increases does its associated wavelength increase or decrease?

The wavelength of waves travelling with the same speed would decrease if the frequency of the waves increases. This is because, speed of a wave is the product of the distance of the wavelength times the frequency of the wave. The velocity of a wave is usually constant in a given medium.


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.

What increases when sound wave travel in solid from gas medium frequency or wavelength?

Velocity increases when sound waves travel from gas medium to solid medium. As velocity = frequency * wave length and the frequency does not change, v is directly proportional to the wave length... Hence the wavelength increases.

When the temperature of a medium increases the speed of sound decreases true or false?

No it is not true. When the temperature of the medium increases the speed of sound in that medium increases.

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 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.


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.


How the wavelength of waves traveling with the same speed would change of the frequency of the waves increases?

The wavelength of waves travelling with the same speed would decrease if the frequency of the waves increases. This is because, speed of a wave is the product of the distance of the wavelength times the frequency of the wave. The velocity of a wave is usually constant in a given medium.
