How does a magnifying glass make a small thing big, and why does a prism split white light? The lens maker's formula and the thin lens formula, power and combinations of lenses, and the prism with minimum deviation and dispersion, with the rainbow and the colours of the sky. It covers the unit of the Indian syllabus (NCERT, NEET, JEE Main) and the matching topic of A-Level, IB and AP.

Prisms, Dispersion and the Rainbow
Physics · High School (9–10) · Prisms and Dispersion of Light
FreeCh 7 · 2/3
Sunlight looks white, but a glass prism or a drop of rain shows that it holds many colours. In this course we follow a ray through a prism, we find why white light splits into a spectrum, and we see how raindrops make a rainbow.
