• a change in the wave velocity when the depth changes

• the wave bouncing off a boundary

• a change in the wave frequency due when the depth changes

• the wave bending around a barrier

In an ideal case (with no loss in energy) when a wave pulse approaches a fixed boundary, it is

• reflected inverted with no change in amplitude

• reflected upright with no change in amplitude

• reflected upright with a decrease in amplitude

• reflected inverted with a decrease in amplitude

When a wave pulse travelling on a light rope reaches the position where it is attached to a heavier rope, what happens?

• the wave is reflected as an inverted pulse with the same amplitude

• the wave is partially transmitted as an upright pulse and partially reflected as an upright pulse, with reduced amplitudes

• the wave is partially transmitted as an upright pulse and partially reflected as an inverted pulse, with reduced amplitudes

• the wave is transmitted as an upright pulse with the same amplitude
