Understanding Light and Frequency Concepts

Mr. KY presents a problem of the week focusing on calculating the frequency of electromagnetic radiation (EMR) with a given wavelength. The video explains the light equation, which relates frequency, wavelength, and the speed of light. It demonstrates algebraic manipulation to solve for frequency and includes unit conversion from nanometers to meters. The solution is presented, and viewers are encouraged to reach out with questions or explore additional resources provided by Mr. KY.
