A foundational part of the MCAT, light and optics bridge the gap between physics and biology, making them vital for your exam preparation.

In this episode, Sam Smith breaks down the fundamentals of light, covering both its wave and particle properties. From the energy of photons and the photoelectric effect, to wave behavior and the principles of refraction and reflection, Sam simplifies complex concepts to help you grasp key equations and principles. You'll also learn about lenses, ray tracing, and the real-life applications of polarization.
