Grade 10 Oceanography and Hydrology
Wave refraction is the
  1. bending of the wave due to shallow ocean floor.
  2. return of the wave after it hits the beach.
  3. forward bending of a wave before it breaks.
  4. redirection of most of the waves destructive energy to the bay.
Grade 10 Oceanography and Hydrology
Wave refraction is the
  1. bending of the wave around a headland.
  2. return of the wave after it hits the beach.
  3. forward bending of a wave before it breaks.
  4. redirection of most of the wave's destructive energy to the bay.
Grade 3 Light and Optics
Grade 10 Oceanography and Hydrology
A result of wave refraction is
  1. wave energy is concentrated on headlands projecting into the water.
  2. wave energy is concentrated in the recessed areas between headlands.
  3. wave energy is largely dissipated before the wave reach the shore.
  4. headlands are enlarged as sediment is deposited on the seaward side.

Grade 8 Light and Optics
Grade 11 Light and Optics
Which of the following is an example of refraction?
  1. A parabolic mirror in a car headlight will focus light into a beam.
  2. A fish appears closer to the surface of the water than it really is when observed from a riverbank.
  3. In a mirror, when you lift your right arm, the left arm of your image is raised
  4. Light creating interference patterns.
Grade 4 Waves and Sound
Grade 12 Physics
What is the refractive index of a medium?
  1. A measure of how fast the wave travels through the medium
  2. The ratio of the angle of incidence to the angle of refraction
  3. A dimensionless number indicating how much a wave slows down in a medium
  4. A unit of frequency for sound waves
Grade 8 Waves and Sound
The two main components of a sound wave are                            .
  1. reflection and refraction
  2. compression and refraction
  3. compression and rarefaction
  4. reflection and rarefaction
Grade 8 Waves and Sound
Refraction occurs when a wave                                                          .
  1. passes through a medium without any change
  2. bounces back from an obstacle
  3. bends as it passes from one medium to another at an angle
  4. spreads out when it encounters a new medium
Grade 8 Light and Optics
What does the refractive index depend on?
  1. The speed of light in a vacuum.
  2. The color of the light.
  3. The angle of refraction.
  4. The nature of the medium, physical conditions, and color of the light.
