Explanation:
Answer:
The critical angle for the liquid when surrounded by air is 30 degrees.
Explanation:
Given that,
The angle of incidence is 33.5° and the angle of refraction is 19.3°. Firstly, we can find the refractive index of the liquid. It can be calculated using Snell's law as :
The critical angle is given by :
Here, is refractive index of air and is refractive index of liquid.
So, the critical angle for the liquid when surrounded by air is 30 degrees.
