Answer:
Well such a question can be solved by using Snell's Law.
Medium 1 is water.
It's refractive index (n1) is 4/3.
Medium 2 is Glass.
It's refractive index (n2) is 3/2.
So the formula goes as follows
Where i is the angle of incidence and r is the angle of refraction.
Solve this equation.
r = 26.387799 degrees. (approximately)
You can check the answer since as glass is denser than water, the ray travelling from water to glass goes towards normal hence angle or refraction is less than angle of incidence.
You can solve any of these kind of problems by the above given simple formula.
Hence the Angle of refraction is
26.387799°
