Question

Name the process represented by the figure.
State the two laws related to the process.​

Answer 1

Answer:

(a) refraction

(b) laws of refraction:

* All the rays i.e. incident ray , normal  and refracted ray all lie in the same  plane.

* Snell's law:

sine of angle of incidence by sine of  angle of refraction is constant for a

particular pair of medium.

sin i/ sin r = constant

HAVE A NICE DAY

Answer 2

Answer:

• the process shown here is refraction.
• the laws here is that the angle of incidence (in first medium)= angle of reflection (in the second medium)
• all the things here lies on a single plane
