Detailed explanation-1: -Frequency of a wave is the number of successive crests (or troughs) passing a given point in 1 second. Q. 50 waves pass through a point in 0.1 second. If the distance between the crest and adjacent trough of the wave is 0.34 m.
Detailed explanation-2: -FREQUENCY. The number of crests that pass a given point within one second is described as the frequency of the wave. One wave-or cycle-per second is called a Hertz (Hz), after Heinrich Hertz who established the existence of radio waves. A wave with two cycles that pass a point in one second has a frequency of 2 Hz.
Detailed explanation-3: -The frequency of a wave is the number of complete waves that pass a given point in a certain amount of time. Frequency can also be described as the number of vibrations per second.
Detailed explanation-4: -The number of complete waves produced in one second, or the number of vibrations/oscillations of the sound wave travelling through medium per second is called frequency of the wave. The SI unit of frequency is hertz (Hz).
