Question

What is the frequency of radiation whose wavelength is 11.5 a0 ?

Answer 1

The frequency of radiation is
`2.61 * 10^(17) s^(-1)`

Step-by-step explanation:

Given:

Wavelength
`\lambda = 11.5 * 10^(-10)` m

Speed of light
`c = 3 * 10^(8)`
`(m)/(s)`

For finding the frequency of radiation,

`c = f \lambda`

`f = (c)/(\lambda)`

`f = (3 * 10^(8) )/(11.5 * 10^(-10) )`

`f = 2.61 * 10^(17)`
`s^(-1)`

Therefore, the frequency of radiation is
`2.61 * 10^(17) s^(-1)`
