3.2 The Wave Nature of Light: Wavelength, Frequency, Speed of Light & Interference

Chapter 3: Quantum Theory and Electronic Structure | Lecture 2 of 10 General Chemistry: The Complete College Lecture Series This chapter covers the wave nature of light, the photoelectric effect, the Bohr model, the de Broglie wavelength, the uncertainty principle, quantum numbers, orbitals and electron configurations. This lecture introduces the wave nature of light, the first step toward understanding the electronic structure of atoms. Starting from the light and heat that the Sun produces by fusing hydrogen into helium, we look at the electromagnetic spectrum from gamma rays to radio waves, and how energy and frequency are directly related. We define the key properties of a wave (wavelength, frequency and amplitude), see that light travels as perpendicular electric and magnetic waves at a constant speed, and learn the equation c = (wavelength) x (frequency). We then explore constructive and destructive interference and the double-slit experiment as proof that light behaves as a wave, and finish with a worked example calculating the frequency of laser light from its wavelength, paying close attention to unit conversions. These are comprehensive general chemistry lecture videos, built to help students succeed in the course, with clear step-by-step explanations, closed captions and practice quiz questions.
