Question

8. What is the frequency of green light waves that have a wavelength of 5.2 x 10-7 m.? The speed of light is 3.0 x 108 m/s

Answer 1

`f=5.76* 10^(14)\ Hz`

Step-by-step explanation:

We need to find the frequency of green light having wavelength o
`5.2* 10^(-7)\ m`. It can be calculated as follows :

`c=f\lambda\\\\f=(c)/(\lambda)\\\\f=(3* 10^8)/(5.2* 10^(-7))\\\\f=5.76* 10^(14)\ Hz`

So, the required frequency of green light is equal to
`5.76* 10^(14)\ Hz`.
