Question

I got the answer r=sin^-1(1/√3) how to change it into degrees.​

Answer 1

Answer:

35°16'

Explanation:

Angle of incidence i=sin

−1

(

2

3

)=sin

−1

(sin60

o

)=60

o

Using μ=

sinr

sini

⇒sinr=

μ

sini

=

1.5

sin60

o

=

1.5

0.8660

We get sinr=0.5773

Thus angle of refraction r=sin

−1

(0.5773)=35

o

16
