2. In which type of wave are the vibrations in the same direction a s the wave is travelling?

  • Longitudinal
  • Transverse

3. What is the focal length?

  • The distance from the outside of the lens to the focal point
  • The distance from the object to the focal point
  • The distance from the centre of the lens to the focal point
  • The distance from the object to the lens

4. What happens when a wave hits a boundary at an angle?

  • It speeds up and maintains the same direction
  • It slows down and refracts (one half has hit the boundary first and slows down before the other half causing it to refract)
  • It slows down and maintains the same direction
  • It speeds up and refracts ((one half has hit the boundary first and speeds up before the other half causing it to refract)

5. What happens when a wave hits a boundary 'face on'?

  • It slows down and refracts
  • It speeds up and refracts
  • It slows down and maintains the same direction
  • It speeds up and maintains the same direction
