Answer 1

A light wave moves from diamond (n = 2.4) into water (n = 1.33) at an angle of 24°. What angle does it have in water?

Answer 2

be careful to keep n1, n2, theta1, and theta 2 straight

Answer 3

2.4/1.33=sin(24)?

Answer 4

0.55

Answer 5

yeah it also works if you put 2.4 as n1, it just needs to be

2.4/1.33 = sin(x)/sin(24)

since 2.4 and the angle 24 are n1 and theta 1

Answer 6

2.4/1.33 = sin(x)/sin(24)

=0.55

Answer 7

so that would be the final answer right

Answer 8

uh not quite

2.4/1.33 = sin(x)/sin(24)

solving for sin(x) gives us

(2.4/1.33) * sin(24) = sin(x)

then take the arcsin of both sides to get the angle

Answer 9

x = arcsin[(2.4/1.33) * sin(24)] = 47.22 degrees = your solution
