Flashcards on Wave Motion
Click on the flashcard to see the answer
What is wave motion?
Wave motion is the transfer of energy through the vibration of particles or disturbances in a medium.
What are the two types of waves?
The two types of waves are longitudinal waves and transverse waves.
Name an example of a longitudinal wave.
Sound waves are an example of longitudinal waves.
Name an example of a transverse wave.
Light waves are an example of transverse waves.
What is the wavelength of a wave?
The wavelength is the distance between two corresponding points on a wave, such as the crest to crest or trough to trough.
What is the amplitude of a wave?
The amplitude is the maximum displacement of a particle from its rest position.
What is the frequency of a wave?
The frequency is the number of complete waves that pass a point in one second.
What is the speed of a wave?
The speed of a wave is the distance it travels per unit of time.
What happens to the frequency of a wave if the wavelength decreases?
If the wavelength decreases, the frequency increases.
What is the relationship between wave speed, frequency, and wavelength?
Wave speed is equal to the product of frequency and wavelength.
What property of a medium affects the speed of sound waves?
The density and elasticity of a medium affect the speed of sound waves.
What is the Doppler effect?
The Doppler effect is the change in frequency or wavelength of a wave in relation to an observer who is moving relative to the wave source.
What is interference in wave motion?
Interference is the interaction of two or more waves that meet.
What is constructive interference?
Constructive interference occurs when two waves combine to increase the amplitude.
What is destructive interference?
Destructive interference occurs when two waves combine to decrease the amplitude.
