Answer:
Angle of refraction in the glass is 32 degrees
Explanation:
It is given that,
Maurice directs a beam of light on a sheet of glass at an angle, θ₁ = 51°
The refractive index of the glass is, n₂ = 1.46
We know that the refractive index of the air is, n₁ = 1
We have to find angle of refraction in glass i.e. θ₂
According to Snell's law :
[tex]\dfrac{n_1}{n_2}=\dfrac{sin\ \theta_2}{sin\ \theta_1}[/tex]
Putting all the values we get :
[tex]\dfrac{1}{1.46}=\dfrac{sin\ \theta_2}{sin51}[/tex]
[tex]\theta_2=sin^{-1}(\dfrac{sin(51)}{1.46})[/tex]
[tex]\theta_2=32\ ^0[/tex]
Hence, the correct option is (c) " 32 degrees ".
