Burst your bubble

Classical Mechanics Level 3

An air bubble is trapped in a liquid.A ray of light enters the bubble at angle of 60 ° 60° to its surface and then it deviates by an angle of 30 ° 30° after undergoing refraction.

Can you find the refractive index of the liquid?

Details and assumptions

Refractive index of air is 1 1 and the liquid has a greater refractive index than air. The ray of light is monochromatic (single colour).
