Question 1

What happens to the emergent ray when light passes through a rectangular glass slab?

  • It diverges
  • It converges
  • It remains parallel to the incident ray

💡 Hint: Consider the properties of the glass slab.

Question 2

True or False: The angle of incidence affects the amount of lateral displacement.

  • True
  • False

💡 Hint: Think about the light's bending as the angle increases.

Challenge Problems

Push your limits with challenges.

Question 1

Calculate the lateral displacement of a light ray entering a glass slab of thickness 5 cm at an angle of incidence of 30° and a refractive index of 1.5. Use the appropriate formula that relates these elements.

💡 Hint: First, find the angle of refraction using Snell's Law.

Question 2

If the refractive index of a material is 1.3, and the angle of incidence is 60°, what is the angle of refraction? Also, discuss what implications this angle might have for optical devices.

💡 Hint: Remember to use the refractive index in context and apply the concept of ray paths.
