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 of photon=?

Wavelength of photon($\lambda$) = 1040 nm

= 1040 × 10^-9 m

$\nu$ = C/$\lambda$

C= velocity of light ( 2.99× 10⁸ m/s)

Frequency= 2.99×10⁸ m s^-1 / 1040×10^-9 m

Frequency of photon is

= .002875 × 10¹⁷

= 2.875 × 10¹⁴ s^-1
