Exploring the Electromagnetic Spectrum

This video tutorial covers the electromagnetic spectrum, explaining the properties of electromagnetic waves, including their speed, wavelength, and frequency. It discusses the relationship between energy and frequency, using Planck's constant. The video includes practice problems to help understand the concepts of wavelength and frequency, and provides calculations for the frequency and energy of photons, specifically UVA radiation. It concludes with converting energy from joules to electron volts.
