Contemporary Physics: Part 2 Lecture № 5 Snell's law Wavefronts from a point source in the context of Snell's law. The region below the grey line has a higher index of refraction , and proportionally lower speed of light , than the region above it.

Contemporary Physics: Part 2 Lecture № 5 Prism Dispersion causes separation of colors when light is refracted by a prism. Wavelength is decreased in a medium with higher refractive index. Wavefronts from a point source in the context of Snell's law. The region below the grey line has a higher index of refraction , and proportionally lower speed of light , than the region above it.

Contemporary Physics: Part 2 Lecture № 5 Superposition principle The net response at a given place and time caused by two or more stimuli is the sum of the responses which would have been caused by each stimulus individually. So that if input A produces response X and input B produces response Y then input (A + B) produces response (X + Y).
