Question

A shade of yellow light with a wavelength of 5.8×10-7 m and a frequency of 5.17 × 10-14 Hz

Answer 1

Explanation:

We have,

The wavelength of yellow light,
`\lambda=5.8* 10^(-7)\ m`

Frequency of yellow light,
`f=5.17* 10^(-14)\ Hz`

It is assumed to find the speed of light in the yellow light.

The speed of a wave is given in terms of wavelength and frequency as :

`v=f\lambda\\\\v=5.17* 10^(-14)* 5.8* 10^(-7)\\\\v=2.99* 10^(-20)\ m/s`

So, the speed of light in a shade of yellow light is
`2.99* 10^(-20)\ m/s`.
