Light passes from benzene (medium1)to water (medium 2) in Figure 20at (a)1=30or (b)1=0. Find the angle2in each case.

Short Answer

Expert verified

a) For1=302=34.33,

b) For 1=02=0,.

Step by step solution

01

Concept used.

The Snell's law is:

n1蝉颈苍胃1=n2蝉颈苍胃2.

02

Find the angle θ2 in θ1=30°

a)

Consider the angle1=30 that is made by light when it passes from benzene to water.

The angle2is:

1.50sin30=1.33sin2sin2=1.50sin301.33sin2=0.563912=34.33

03

Find the angle θ2 is θ1=0°

b)

An angle1=0 is made by light when it passes from benzene to water.

The angle 2is:

1.50sin0=1.33sin2sin2=1.50sin301.33sin2=02=0
