please include diagram i am a visual learner and it helps me follow the process!

An aquarium filled with water has flat glass sides whose index of refraction is 1.52. A beam of light from outside the aquarium strikes the glass at an angle of 38.0° as measured from the surface of the glass to the incident light ray. What is the angle of refraction of this light ray when it enters (a) the glass, and then (b) the water? (c) What is the critical angle from the glass to the water? Given the following: nair = 1.00 and nwater = 1.33. (d) Provide a detailed ray diagram of the situations. [Diagram 3 pts.]
