A ray of light incident on a liquid-to-glass interface at an angle of 35 degree.

Question

A ray of light incident on a liquid-to-glass interface at an angle of 35 degree. Indices of refraction for the liquid and glass are, respectively, 1.63 and 1.52. What is the angle of refraction for the ray moving through the glass? 23 degree 30 degree 38 degree 46 degree Charge A has 10 electric field lines coming out, Charge B has 20 lines coming out, and Charge C has 30 lines coming in. which pair of these charges will have the largest force between them if placed one cm apart? A and B B and C C and A more information is needed

Explanation / Answer

23.

Given theta 1 = 35

n1 = 1.63

n2 = 1.52

theta 2 = ?

n1 * sin(theta1) = n2 * sin(theta 2)

1.63 * sin(35) = 1.52 * sin(theta 2)

angle of refraction theta 2 = 37.95

c. 38------------Answer

24.

force is directly proportional to the product of the charges

the largest force is

b. B and C
