Question

Using snell's law. Determine what angle a light wave bends at when it
leaves air and enters water at an angle of 30 degrees.

Answer 1

Answer:

Angle of refraction is 23° .

Explanation:

$\frac{ \sin(0w) }{ \sin(0a) } = \frac{n \: a}{n \: w}$

$\frac{ \sin(30) }{ \sin \: 0a } = \frac{1.3}{1.0}$

$\sin \: 0w \: = \: \frac{ \sin(30) }{1.3}$

$= 0.3846153846$

$\sin^{ - 1} (0.3846153846$

$0w \: = \: 23 ^{o}$
