Properties of Waves Quiz

What does the amplitude of a wave represent?

• The height of the crest above the rest position

• The distance between two crests

• The number of waves that pass a point in one second

• The depth of the trough below the rest position

Which property of a wave is directly related to its pitch in the context of sound waves?

• Frequency

• Crest

• Trough

• Amplitude

What happens when light waves travel from air into water?

• Their frequency increases

• They slow down

• They speed up

• Their amplitude decreases

Which phenomenon occurs when waves bend around the edge of an obstacle?

• Reflection

• Refraction

• Diffraction

• Absorption

What does the law of conservation of mass state in the context of wave properties?

• Energy cannot be created or destroyed, only transformed

• Mass cannot be created or destroyed in a closed system

• The frequency of a wave remains constant as it travels through different mediums

• The amplitude of a wave is conserved through different mediums
