Question

The frequency of yellow light having wavelength 600 nm is

Answer 1

frequency=speed of light/wavelength.
=3*10^8/6*10-7=10^15/2=5*10^14s^-1

Answer 2

Answer: The correct answer is  $5\times 10^{14}Hz$.

Explanation:

The expression for the frequency in terms of the wavelength is as follows;

$f =\frac{c}{\lambda}$

Here, f is the frequency of the wave, $\lambda$ is the wavelength of the wave and c is the speed of the light.

It is given in the problem that the wavelength of yellow light is 600 nm.

Calculate the frequency of the yellow light.

$f =\frac{c}{\lambda}$

Put $\lambda= 600 nm$ and $3\times 10^{8}m/s$.

$f =\frac{3\times 10^{8}m/s}{600\times 10^{-9}m}$

$f =5\times 10^{14}Hz$

Therefore, the frequency of the yellow light is $5\times 10^{14}Hz$.
