Wave Properties Answer Key
Explore the properties of waves including amplitude, wavelength, frequency, and wave speed.
Prior Knowledge Questions
Q1.What is a wave?
A wave is a disturbance that transfers energy from one place to another without transferring matter.
Q2.What is the difference between transverse and longitudinal waves?
In transverse waves, particles move perpendicular to wave direction; in longitudinal waves, particles move parallel to wave direction.
Q3.What is wavelength?
Wavelength is the distance between two consecutive crests (or troughs) of a wave, measured in meters.
Activity A – Wave Measurements
Q1.What is the relationship between frequency and wavelength?
Frequency and wavelength are inversely related: as frequency increases, wavelength decreases (wave speed = frequency × wavelength).
Q2.What is amplitude and what does it represent?
Amplitude is the maximum displacement of a wave from its rest position; it represents the energy of the wave.
