Do the colours of white light travel at same speed through the air?
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..
Statement 1: When white light ray passes through a prism, it disperses into seven different colours, and this phenomenon is called dispersion.
Statement 2: In a refracting media, lights of different colour travel at different speed.

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. That last statement is not exactly true but the reasons are complicated and you …
In a vacuum, where the index of refraction is unity, all colors travel at the same velocity. However, in transparent materials with varying indices of refraction, colors with shorter …
So the answer to your question is, that in vacuum, the different wavelength light all travel always at speed c when measured locally, but in a medium, the speed of light is dependent on its wavelength.
Lights of all colour travel at the same speed in vacuum. Statement 1: When white light ray passes through a prism, it disperses into seven different colours, and this phenomenon is …
Why do different colors of light travel at the same speed? Light is made up of electromagnetic waves, and the speed of these waves is determined by the properties of the …
I know that red light travels faster in non-air mediums than blue light because of its wavelength, but I'm not understanding why this doesn't happen in a vacuum? This is related to …
