Planck's Constant and Photon Energy

The video tutorial explains how to calculate the energy carried by a photon using its frequency. It introduces Planck's constant, denoted as 'h', and demonstrates the calculation process by multiplying the constant with the given frequency. The tutorial includes a detailed explanation of multiplying powers of ten and concludes with the final energy result in joules.
