Answer to Question #98483 in General Chemistry for Tera

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

Wavelength λ =1040nm= 1.04*10^-6

$C = λf$ ; where C is the speed of light =3*10^8.

Frequency of photon$f = C/ λ$

 f = 3*10^8/1.04*10^-6

f= 2.89*10^14 Hz
