Worked practice questions

Snell's law states that the ratio sin(i)/sin(r) for two media is:

  1. Variable
  2. Constant for given media
  3. Equal to 1
  4. Equal to 0
Show answer and solution

Correct answer: B. Constant for given media

sin(i)/sin(r) = n21, the refractive index of medium 2 relative to medium 1. This ratio is constant for any pair of media.

The wavefront from a point source is:

  1. Planar
  2. Spherical
  3. Cylindrical
  4. Cuboidal
Show answer and solution

Correct answer: B. Spherical

Light from a point source spreads out in all directions, so wavefronts are concentric spheres centered on the source.

Young's double-slit experiment demonstrates which phenomenon?

  1. Refraction
  2. Interference of light
  3. Reflection
  4. Polarization
Show answer and solution

Correct answer: B. Interference of light

Young's double-slit experiment was the classic demonstration of interference of light. Two coherent waves from the slits superpose to produce a pattern of bright and dark fringes.
