Question

Do all colours of white light move with same speed?
Yes or no?

Answer 1

Answer:

please mark it as brainliest answer please dear ❤️.

Explanation:

In empty space, all colors travel at the same speed called c. Light of different wavelengths, or colours, travels at different speeds when they travel through any medium other than vacuum.

Answer 2

Yes, All the colours of the white light move with the same speed.

Explanation:

Air is not a diffusion medium, so light travels at equal velocities (speeds) of all wavelengths.                      

• The speed of light does not change when it propagates through one single medium.  

• The speed of light propagation depends on the electromagnetic properties of the medium in which it travels.    

• The speed of light of different colours changes when the medium changes.  

• The range of colours of the rainbow is violet, indigo, blue, green, yellow, orange, red. We can remember it as VIBGYOR.

• VIBGYOR stands for Violet, Indigo, Blue, Green, Yellow, Orange and Red.

• VIBGYOR is the representation of colours after the split of white light.
