yes
Waves often appear as a series of crests called wave trains. These wave trains consist of multiple individual waves following one another in succession.
No, the distance from the trough of one wave to the trough of another wave is not the wave amplitude. The wave amplitude refers to the maximum displacement of a point on a wave from its equilibrium position.
Destructive interference. This occurs when the crest of one wave meets the trough of another wave, leading to a cancellation of the wave amplitudes at that point.
constructive interference
The frequency and wavelength of the wave cannot change as it travels from one medium to another.
Refraction is the change in direction of a wave as it passes from one medium to another. This change occurs because the wave changes speed when it moves from one medium to another, causing it to bend.
They add up.
wave
When the crest of one wave overlaps the crest of another wave, they combine to create a larger wave. This is known as constructive interference, where the amplitudes of the two waves add up to create a wave with a higher amplitude.
The wave that carries energy from one place to another is called a mechanical wave. Examples of mechanical waves include sound waves and seismic waves.
When the crest of one wave coincides with the crest of another wave, they interfere constructively, producing a wave with an amplitude equal to the sum of the individual wave amplitudes. This results in an increase in wave height at that location, known as constructive interference.
