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

Angle of refraction is 23° .

Step-by-step explanation:

`( \sin(0w) )/( \sin(0a) ) = (n \: a)/(n \: w)`

`( \sin(30) )/( \sin \: 0a ) = (1.3)/(1.0)`

`\sin \: 0w \: = \: ( \sin(30) )/(1.3)`

`= 0.3846153846`

`\sin^( - 1) (0.3846153846`

`0w \: = \: 23 ^(o)`
