Question 1
A light ray in water strikes the water-air boundary with an angle of incidence of 30°. Calculate the angle of refraction.
💡 Hint: Set up the relationship with Snell's law.
Question 2
If the critical angle for glass to air is approximately 42°, what can be inferred about the refractive index of glass?
💡 Hint: Relate the critical angle's sine to the refractive indices.
