When the source of a wave is moving relative to an observer of the wave what happens?
If the source of a wave is moving towards the observer, the observer will perceive a higher frequency (blue shift) in the wave. If the source is moving away, the observer will perceive a lower frequency (red shift) in the wave. This is known as the Doppler effect.
What is the change in pitch or wave frequency due to a moving wave source?
When a wave source is moving towards an observer, the pitch or frequency of the wave increases, known as a Doppler shift. This occurs because the waves are reaching the observer at a faster rate due to the source moving closer. Conversely, when the wave source is moving away from the observer, the pitch or frequency decreases.
What happens to the wave when you decrease the wave period?
When you decrease the wave period, the wavelength becomes shorter and the frequency increases. This results in the wave moving faster.
What is a wave moving at a parallel angle?
A wave moving at a parallel angle is called a transverse wave. In transverse waves, the particles of the medium move perpendicular to the direction of the wave. Examples include light waves, water waves, and seismic S-waves.
What is a wave moving at a right angle to its medium?
A wave moving at a right angle to its medium is called a transverse wave. In this type of wave, the particles of the medium move perpendicular to the direction of the wave propagation. Examples of transverse waves include light waves, electromagnetic waves, and waves on a string.
