Refraction
Summary
The content delves into the principles of refraction and total internal reflection, focusing on Snell's Law, the behavior of light as it passes through different media, and the conditions under which total internal reflection occurs.
- Refraction is described by Snell's Law, highlighting how light bends when transitioning between materials of different refractive indices.
- The relationship between the index of refraction, light's velocity, and wavelength is explored, emphasizing that while frequency remains constant, velocity and wavelength change upon entering a new medium.
- It is clarified that the index of refraction must be greater than or equal to one, debunking the possibility of light traveling faster than its speed in a vacuum.
- Total internal reflection is explained, including the critical angle condition that determines whether light will refract out of or reflect within a material.
