State whether the following statements are true or false:

The maximum displacement of the particle of medium on either side of its mean position is called the amplitude of wave.The number of vibrations made by a particle of the medium in one second is called the frequency of the waves.The distance travelled by the wave in one time period of vibration of particle of medium is called its wavelength.

Detailed Solution

The given statement is true.
Concept- The definition of amplitude is simply the maximum distance covered by an object. Wavelength appears to be a measure of distance. In a wave, the distance between two successive or neighbouring points. Frequency is just the rate at which something repeats itself. The same as metro frequency.
Consider the amplitude of a pendulum in a watch. If you pay attention, you will see that the pendulum in a watch never moves beyond a particular distance from its centre point. That is its greatest distance and the centre point or position known as the mean position. So amplitude is the maximum distance spanned by an object or subpart on each side of its means positions. It is commonly represented by the letters an or A.
See the sine wave graph for more information. The wavelength is the distance covered from 0 to 2. I hope you have a mental picture of what I mean. The distance travelled by a wave in one complete cycle in a given medium is referred to as its wavelength. It is commonly symbolised by The wavelength in interference is just the space between two consecutive crests or troughs. The wavelength of a sound wave is the space between two consecutive or contiguous compression or rarefaction.

Where v is the velocity
f stands for frequency.
Frequency: Consider the metro system. If you stand near a metro station, you will commonly hear individuals say ``metro frequency.' So, what exactly is it? How many times the metro arrives at stations over a set period of time. This is known as frequency. It is the number of vibrations produced by a particle or item in a given medium per second/period. It is commonly represented by f or.
Hence, the given statement is true.
