Question 5
F

A student measures the angles of a ray entering a glass block. Both angles are measured from the surface instead of from the normal.

The student records an incident angle of 50∘ 50^\circ\,50∘ and a refracted angle of 65∘65^\circ65∘.

Which pair gives the correct angles of incidence and refraction?

[1]
A

Incidence 40∘40^\circ40∘; refraction 25∘25^\circ25∘.

B

Incidence 50∘50^\circ50∘; refraction 65∘65^\circ65∘.

C

Incidence 25∘25^\circ25∘; refraction 40∘40^\circ40∘.

D

Incidence 65∘65^\circ65∘; refraction 50∘50^\circ50∘.
