Question

Determine the frequency of light with a wavelength of 4.27 * 10^-7

Answer 1

`f=7.02*10^15`

Step-by-step explanation:

We are supposed to find the frequency of light .

λf=c

the abow formula is the relation for frequency and wavelength.

Here c is the speed of light.

`c=3*10^9m/s`

Given that

λ=
`4.27 * 10^-7`

by substituting all this we get f as,

`f=(3*10^9)/(4.27 * 10^-7)`

`f=7.02*10^15`
