Photon Frequency and Wavelength Concepts

The video tutorial focuses on solving problems related to the wavelength and frequency of photons. It begins with calculating the wavelength from a given frequency using the speed of light. The tutorial then covers unit conversions, such as converting meters to micrometers and nanometers. It also explains how to calculate frequency from wavelength and vice versa. The relationship between energy and frequency is explored using Planck's constant, and the tutorial concludes with a final problem on determining wavelength from energy.
