Question

The speed of light in air 1. depends only on the frequency of the light. 2. depends on both the wavelength and the frequency of light. 3. depends only on the wavelength of light. 4. is independent of the wavelength and frequency of light.

Answer 1

2. depends on both the wavelength and frequency of light.

Explanation: Speed of light(v)=wavelength×Frequency.

∴speed of light depends on both wavelength and frequency as shown from the equation above.
