Question: If the angle of incidence is equal to the angle of refraction, what is the medium?

Options:

  1. Vacuum
  2. Air
  3. Glass
  4. Optically denser medium

Correct Answer: Vacuum

Solution: 

According to Snell\'s law, if the angle of incidence equals the angle of refraction, the light is traveling in the same medium, which can be vacuum or air.

Questions & Step-by-Step Solutions

If the angle of incidence is equal to the angle of refraction, what is the medium?
  • Step 1: Understand what angle of incidence means. It is the angle at which light hits a surface.
  • Step 2: Understand what angle of refraction means. It is the angle at which light bends as it enters a new medium.
  • Step 3: Recall Snell's law, which states that the relationship between the angles of incidence and refraction depends on the mediums involved.
  • Step 4: If the angle of incidence is equal to the angle of refraction, it means there is no bending of light.
  • Step 5: Conclude that if there is no bending, the light is traveling in the same medium, which can be either air or vacuum.
  • Refraction and Snell's Law – Refraction occurs when light passes from one medium to another, and Snell's law relates the angles of incidence and refraction to the indices of refraction of the two media.
  • Medium Properties – Different media have different refractive indices, and when the angle of incidence equals the angle of refraction, it indicates that the light is not changing medium.
