Electromagnetic Waves and Frequency Concepts

Mr. Franklin introduces the concept of light as electromagnetic radiation, covering both visible and non-visible spectrums. He explains wave properties using Greek letters lambda and nu, and discusses frequency measured in Hertz. The video also explores the relationship between energy, frequency, and wavelength, emphasizing how these concepts apply to different types of electromagnetic waves.
