When a wave moves throgh an opening in a barrier?
When a wave moves through an opening in a barrier, it diffracts, spreading out into the region beyond the barrier. This diffraction phenomenon occurs because the wave bends around the edges of the barrier, resulting in a curved wavefront. The extent of diffraction depends on the size of the opening and the wavelength of the wave.
What is it that moves from source to receiver and wave motion?
The wavelength of a transverse wave is the distance between successive crests.
How does the speed of a wave source and the speed of waves themselves compare when a bow wave is being produced?
A bow wave is produced when the speed of the source exceeds the natural speed of surface waves in the medium (water). This effect is characterised by the disturbance spreading out in a 'V' formation behind the boat.
Why is a mechanical wave not always produced when a source vibrates?
A mechanical wave is only produced when a vibrating source has a medium to propagate through. If the source is vibrating in a vacuum, for example, no mechanical wave will be produced because there is no medium for the wave to travel through.
What is the changing in pitch due to a moving wave source?
As a wave source moves towards an observer, the pitch of the wave increases. This is known as a Doppler shift, where the frequency of the wave appears higher due to the relative motion between the source and the observer. Conversely, as the source moves away from the observer, the pitch of the wave decreases.
Why is a bow wave produced when a wave source moves?
Like the Doppler effect, the source of the waves is moving, this time in the same direction as the wave front and therefore catching up to the waves that were produced earlier, resulting in a bunching up effect of waves in front of the source and a spreading out of wave fronts behind the source.

What is a longitundinal wave?
If the wave moves in the same direction as the force that produced it.

What moves from source to receiver in wave motion?
Energy.
What happens when a wave passes a barrier or moves through a hole in a barrier?
When a wave passes a barrier, it can diffract, which means it bends around the edges of the barrier. If the wave encounters a hole in a barrier, it can undergo diffraction and interfere with itself, creating patterns of constructive and destructive interference on the other side of the barrier or hole.
What is the source of a sound wave and how does it propagate through a medium?
The source of a sound wave is vibrations produced by an object. These vibrations create changes in air pressure, which travel through the air as a wave. As the wave moves through a medium, such as air or water, the particles in the medium vibrate back and forth, transmitting the sound energy.
How are frequency wave produced?
Frequency waves are produced by a vibrating source, such as a sound wave produced by a vibrating object or an electromagnetic wave produced by an oscillating electric charge. The rate at which the source vibrates determines the frequency of the wave.
What happens to the amplitude of a wave as it moves away from its source?
The amplitude of a wave typically decreases as it moves away from its source. This is due to the spreading out of the wave energy over a larger area as it propagates. Factors such as distance, intervening materials, and absorption can also affect the amplitude of the wave.
