This lecture is about Snell's law of refraction of light. I will teach you all the important concepts of Snell's law.
Q: What is Snell's law of refraction of light?
Ans: Snell's law states that the ratio of the sine of the angle of incidence to the sine of angle of refraction remains constant until medium is the same.
To learn more about Snell's law of refraction, watch this lecture.

Here is another Noteworthy point, along with the same medium for refractive Index we should give an account for color too because colors have different Wavelengths since you may have seen when a light is passed through a prism the bottom color (last) is violet, and top in red, it is because violet (also blue) has lower wavelength and red (also orange) has more wavelength... Less wavelength=more bend towards normal and vice versa
