Question

calculate the wavelength of a photon with a frequency of 2.36x10^19 Hz

Answer 1

In order to solve this problem, it is necessary to be familiar with the following equation: c=λv, where c=speed of light (3.0 x 10⁸ m/s), λ=wavelength, and v=frequency. Recall also that Hz = 1/s = s^-1. We can then solve for λ and plug our values in:

λ= c / v = (3.0 x 10^8 m s^-1) / (2.36 x 10¹⁹ s^-1) = 1.27 x 10^-1 m
