Answer to Question #213666 in Electric Circuits for amit

Question

 A ray of light in corn oil is incident striking with an angle of incidence of 40 degrees on water. Calculate the angle of refraction to the nearest degree

Answer 1

$Gives$

$$n_i=1.48,n_w=1.33 ,i=40°,r=?$$

$n_isin\theta_i=n_wsin\theta_r$

$1.48\times sin40°=1.33 \times sin\theta_r$

$1.48\times0.642=1.33\times sin\theta_r$

$sin\theta_r=0.7145$

$\theta_r=46°$
