Question

Pls answer in a little detail i am giving u 25 points answer properly pls

Answer 1

Answer:

(a)medium 1 is rarer medium And medium 2 is denser medium.

(b)This phenomenon is called total internal refraction. When light travels from a denser medium to a rarer medium, it bends away from the normal, as illustrated to the left. This behavior follows from Snell's Law. As you saw before, the larger angle must be in the medium having the lower index of refraction.

Answer 2

(a) medium 2 is rarer.

(b)When a ray of light enters a denser medium ,it always bends towards the normal.So the angle of refraction will be less than the angle of incidence (√i=✓r)
