Question

write down 2 laws of refraction ​

Answer 1

Answer:

Suppose there is only one fish in the aquarium. But still, it appears to be many. Or while traveling on a road on a hot summer day, distantly, water appears in the middle of the road out of no-where. Do you know how this happens? This is all due to the refraction. Let us study more about refraction.

Answer 2

Answer:

➊The incident ray, reflected ray and the normal, interface at two medium lies on a same plane

➋The ratio of the sine of angle of incidence to the sine of angle of refraction is always be a constant and this is known as snell's law

sin i / sin r = a constant

This constant is known as refractive index.
