Which one of the folowing frequencies of radiation (in Hz) has a wavelength of 600 nm?

Options

A. `2.0 xx 10^(13)`
B. `5.0 xx 10^(16)`
C. `2.0 xx 10^(14)`
D. `5.0 xx 10^(14)`

Answer

d

Explanation

`lambda=600nm=600xx10^(-9)m`
`c=3.0xx10^(-9)ms^(-1)`
`therefore Frequency.v=c/a=(3xx10^(8))/(600xx10^(-9))`
`5 xx10^(14)Hz`
