Question
Light is incident at an angle of 35 o to the normal of the surface of a pond. From the water (refractive index 1.33) the light appears to be at which angle with respect to the normal to the surface
(a) 49.72 o
(b) 18.53 o
(c) 51.98 o
(d) 25.54 o
(e) 40.28 o
Expert Solution
Step 1
Using Snell's Law, with i and r being the incident and refracted angles and n2,n1 are refractive indexes
sin(i)/sin(r) = n2/n1-----(1)
here i = 35o ,n2=1.33 and n1 =1
