Photon Properties: Wavelength and Frequency Calculations

The video tutorial focuses on solving problems related to the wavelength and frequency of photons. It covers calculations using the speed of light, frequency, and wavelength, including unit conversions to micrometers and nanometers. The tutorial also explains the inverse relationship between frequency and wavelength, and how to calculate frequency from photon energy using Planck's constant. Finally, it demonstrates how to determine the wavelength from photon energy.
