Dez pours carbon tetrachloride (n = 1.46)into a container made of crown glass (n = 1.52).The light ray in glass incident on the glass-to-liquid boundary makes an angle of 30 $\degree$with the normal.Find the angle of the corresponding refracted ray.
A)55.5 $\degree$
B)29.4 $\degree$
C)31.4 $\degree$
D)19.2 $\degree$

Using Snell's Law, we can find the angle of the refracted ray:

n1sinθ1 = n2sinθ2

where n1 is the index of refraction of the incident medium (in this case, glass), θ1 is the angle of incidence, n2 is the index of refraction of the refracted medium (in this case, carbon tetrachloride), and θ2 is the angle of refraction.

Plugging in the given values, we get:

1.52sin30° = 1.46sinθ2

θ2 ≈ 31.4°

Therefore, the angle of the corresponding refracted ray is 31.4°, which corresponds to choice C.
