A light ray strikes a glass interface at an angle of 30°. If the refractive index of glass is 1.5, what is the corresponding angle of refraction in the glass?
💡 Hint: Rearrange Snell's Law to solve for the unknown angle.
If you have a prism made of material with a refractive index 1.67, and light hits it at the critical angle. How would this affect light traveling out of the prism?
💡 Hint: Consider the relationship of the critical angle and its effect on specific incidences.
