The wavelength of red light is 800 nm. Find its frequency. Speed of light = `3 xx 10^(8) m s^(-1).

Text Solution

Verified by Experts

Given : `gamma=800 nm =800xx10^(-9)m=8xx10^(-7)m`
`c=3xx10^(8)m s^(-1)`
Form relation `c=fgamma` ,frequency `f=c/gamma`
or `f=(3xx10^(8))/(8xx10^(-7))=3.75xx10^(14)`Hz.
