Topics of this game:
- When a wave meets a new material and rebounds
- When a wave meets a new material and is transmitted through with a change in direction
- When a wave meets a new material and its energy is transferred to the material, usually as heat
- An imaginary line drawn at 90 degrees to the surface, all angles are measured from this
- The position on a surface where the wave hits it
- The incoming ray
- The outgoing ray when a wave is reflected from a surface
- The outgoing ray when a wave is refracted through a surface
- The angle between the normal line and incident ray
- The angle between the normal line and reflected ray
- The angle between the normal line and refracted ray
- angle of incidence = angle of reflection
- When light is scattered from a surface so no clear image is seen
- When light is reflected off a smooth surface so a clear image can be seen
- When light enters a denser material, it bends _____?_____ the normal line
- A property of the wave that stays the same when it enters a new material
- A property of a wave that gets shorter when it enters a denser material
- The equivalent to a denser material for light waves when looking at water waves
- = mass/volume
- A wave whose oscillations are perpendicular to the energy transfer e.g. light
- A wave whose oscillations are parallel to the energy transfer e.g. sound
- A image formed that can be projected onto a screen because the rays actually cross
- A image formed that can't be projected onto a screen because the rays don't actually cross at the image
