Which light travels in glass with minimum velocity?

Which light travels in glass with minimum velocity?

Violet

Which Colour of light has minimum speed in glass and maximum frequency?

(i) Violet colour has minimum speed in the glass, since it has the minimum wavelength. (ii) Red colour has the minimum frequency.

Which Colour has minimum frequency?

red

What travels in glass with minimum velocity violet green yellow red?

Correct Option: B As light passes from air into glass, there is reduction of velocity. Due to longer wavelengths, red waves travel fastest and is refracted the least, while violet waves travel the slowest and is refracted the most.

For which Colour violet or green does glass have a larger refractive index?

Answer : Violet has a larger refractive index than green since it has a lower wave length.

For which Colour refractive index of glass is maximum?

violet colour

What is the ratio of velocity of red Colour light to velocity of violet Colour light in vacuum?

Answer. In vacuum yes, red and violet light (=single photons or photon packets) travel at the same speed. The frequency of red light is smaller than violet – but the wavelength is longer by precisely the same amount… hence the speed of both colors of light is exactly the same…at least in a vacuum.

What is the velocity of red light in vacuum?

approximately 300,000 kilometers per second

Does violet light travel faster than red?

Violet travels the slowest so it is on the bottom and red travels the fastest so is on the top. This is because what is called the index of refraction, (the ratio of the speed of light in a vacuum to the speed of light in a material), is increased for the slower moving waves (i.e. violet).

What is the ratio of velocity of red Colour light?

It is given that the refractive index of glass for red is 1.618. Let the velocity of red light in glass be v2. This means that 1.618=3×108v2. ⇒v2=3×1081.618=1.85×108ms−1.

What is the speed of red light?

about 400 million million cycles per second
