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

Step-by-step explanation:

We have,

The wavelength of yellow light, $\lambda=5.8\times 10^{-7}\ m$

Frequency of yellow light, $f=5.17\times 10^{-14}\ Hz$

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 :

$v=f\lambda\\\\v=5.17\times 10^{-14}\times 5.8\times 10^{-7}\\\\v=2.99\times 10^{-20}\ m/s$

So, the speed of light in a shade of yellow light is $2.99\times 10^{-20}\ m/s$.
