Sagot :
Answer:
34º
Explanation:
The computation of the angle of refraction in the glass for this ray is shown below:
Given that
the angle of incidence of another red ray is 65º
And, n_1 = 1
n_2 = 1.62
According to shell law
n_1 sin [tex]\theta[/tex]_1 = n_2 sin [tex]\theta[/tex]_r
sin [tex]\theta[/tex]_r = 1 sin 65÷ 1.62
= 0.559
[tex]\theta[/tex]_r = sin^-1 (0.559)
= 34º
