The time taken to complete one full cycle of a wave is called:
Which type of wave requires a physical medium to travel?
Sample Questions
In transverse waves, the particles of the medium oscillate:
Show answer
Perpendicular to the direction of wave propagation.
In transverse waves, the particle displacement is perpendicular to the direction of wave travel. Examples include water waves and light waves.
In longitudinal waves, the particles of the medium oscillate:
Show answer
Parallel to the direction of wave propagation.
In longitudinal waves, the particles oscillate back and forth along the same direction as the wave travels. Sound waves in air are a common example.
Which of the following is an example of a longitudinal wave?
Show answer
Sound waves in air
Sound waves in air are longitudinal because the air molecules vibrate parallel to the direction of wave propagation, creating compressions and rarefactions.
The distance between two consecutive crests of a wave is called:
Show answer
Wavelength
Wavelength is the distance between two consecutive points in phase on a wave, such as crest to crest or trough to trough.
