State Snell’s law of refraction.

1.	State Snell’s law of refraction.
Answer» SNELL’S LAW: The ratio of the sine of the angle of incidence to the sine of the angle of refraction is a constant, for the light of a given colour and for the given pair of media. We have: \(\frac{sin} {sin}\) = constant = µ µ is called the refractive index of the second medium with respect to the first. According to Snell's Law : The sine of angle of incidence to the sine of angle of refraction is always constant for same given medium . Sin i / Sin r = constant = µ And that constant is the refractive index (µ) of the second medium with respect to first medium .

SNELL’S LAW:

The ratio of the sine of the angle of incidence to the sine of the angle of refraction is a constant, for the light of a given colour and for the given pair of media.

We have:

\(\frac{sin} {sin}\) = constant = µ

µ is called the refractive index of the second medium with respect to the first.

According to Snell's Law :

The sine of angle of incidence to the sine of angle of refraction is always constant for same given medium .

Sin i / Sin r = constant = µ

And that constant is the refractive index (µ) of the second medium with respect to first medium .
