Question

Which of the given below options is not a characteristic of the waves.

• A. Amplitude
• B. Frequency
• C. Wavelength
• D. None

Answer 1

The correct option is D

None

Step 1: Explanations of the correct option

In the case of option D,

1. The maximum distance or displacement moved by a point on a vibrating body from its equilibrium position is referred to as amplitude.
2. The wavelength of a wave is defined as the distance between two consecutive rarefactions (R) or two consecutive compressions (C).
3. The number of waves that pass through a fixed point in a given period of time is described by frequency.

Step 2: Explanations for the incorrect options

In the case of option A,

1. The frequency of a wave is the number of waves that pass through a point in a given time.
2. The frequency is measured in $\mathrm{hertz}\left(\mathrm{Hz}\right)$, which is equal to one wave per second.

In the case of option B,

1. The amplitude of a wave is its height, which is generally measured in $\mathrm{meters}$.
2. It is proportional to the amount of energy carried by a wave.

In the case of option C,

1. A wavelength is a distance between identical points in adjacent cycles of crests of a wave.
2. It is also expressed in $\mathrm{meters}$.

Hence, option D is the correct answer.
