Question

What is the frequency of a photon with a wavelength of 1040 nm. Report your answers to three significant digits. The frequency is = _________ s-1

Answer 1

`Frequency=2.88* 10^(14)\ s^(-1)`

Step-by-step explanation:

The relation between frequency and wavelength is shown below as:

`c=frequency* Wavelength`

c is the speed of light having value
`3* 10^8\ m/s`

Given, Wavelength = 1040 nm

Also, 1 m =
`10^(-9)` nm

So,

Wavelength =
`1040* 10^(-9)` m

Thus, Frequency is:

`Frequency=(c)/(Wavelength)`

`Frequency=(3* 10^8)/(1040* 10^(-9))\ s^(-1)`

`Frequency=2.88* 10^(14)\ s^(-1)`
