answer this following Questions
Answers
Answer:
Answer 1- Refraction occurs because light travels through different media at different speeds.
Answer 2- PQ is the incident ray, QM is the angle of refraction, Angle R is the angle of emergence.
Answer 3- When light travels from one transparent medium to another transparent medium of a different density, it bends from its original path at the surface of separation of the two media. This phenomenon of bending of light is called Refraction of light.
Step-by-step explanation:
I hope it helps you army
today only i had my physics test and this chapter came so i remembered everything
Answer:
Snell's law : According to the Snell's law of refraction , the ratio of sine of angle of incidence to the sine of angle of refraction is constant for a given pair of media .
Refractive index =
sine of the angle of refraction
sine of the angle of incidence
Given : Angles of incidence = 60
∘
Angle of refraction = 32.4
∘
Refractive index =
sine of the angle of refraction
sine of the angle of incidence
Refractive index =
sin32.4
∘
sin60
∘
Refractive index =
0.540
0.866
= 1.603
