Part 1 PS Final Review

What is a wave?

• A repeating disturbance that transfers energy through matter or space

• A static object that remains stationary

• A solid object that blocks energy

• A type of sound that cannot travel through space

What is wave frequency?

• The distance between two waves

• The number of wavelengths passing a fixed point each second

• The height of a wave

• The speed of a wave

What happens during the reflection of a wave?

• The wave disappears

• The angle of incidence equals the angle of reflection

• The wave speeds up

• The wave changes color
