It is the Lowest point in a wave the upper point is the crest the bottom point is the trough H
Trough
Waves can interfere constructively, where crest aligns with crest or trough aligns with trough, resulting in an amplified wave. Waves can also interfere destructively, where crest aligns with trough, leading to cancellation of the waves.
it has to do with waves. trough- is the bottom of the wave crest- is the top of the wave
The horizontal distance between the crest or trough of two successive waves is called the wavelength. It is the distance between two corresponding points on a wave, such as from crest to crest or trough to trough.
The letter "B" is typically used to label the trough of a wave.
trough
A perfect vacuum
Constructive interference occurs when waves meet crest to crest or trough to trough, resulting in a stronger wave that is the sum of the individual waves.
wavelength - distance between waves (eg crest to crest or trough to trough)
The wavelength of a wave is the distance between two consecutive points that are in phase. It is usually measured from peak to peak or trough to trough in a transverse wave, or from compression to compression in a longitudinal wave.
Trough. The crest is the highest point of the wave while the trough is the lowest point.
