Answer:

Step-by-step explanation:
We are given that


Angle of incidence,i=37.5 degree
We have to find the angle of refraction into the water made by ray wit the normal to the surface.
Refractive index of water,
By Snell's law




Again for glass water surface
Using Snell's law
Angle of incidence,i'=22.83 degree
