Question

Light travelling in water is incident on air refracts at an angle of 27 degrees. What is the angle of incidence?

my answer: 37 degrees

Answer 1

When light goes from a denser medium to less denser medium then it bends away from the normal ray i.e \(\angle r>\angle i\)

Answer 2

Oh would the answer be 20 degrees?

Answer 3

is there any options ?

Answer 4

You can use snell's law
\(\huge\frac{sin(27°)}{sin \angle r}=\frac{1}{1.33}\)

Answer 5

Now find \(\angle r\)

Answer 6

it will be 37°. You answer was correct !

Answer 7

Oh okay! thanks!
