Question

Cross the odd one out
A. Amplitude
B. Frequency
C. Voltage
D. Wavelength

Answer 1

Hint: As, it is clear that amplitude, frequency, wavelength are defined for any body which is oscillating but voltage is defined for any electric circuit.

 Complete step by step answer:
Amplitude- In mechanics, amplitude is the maximum displacement or distance shifted by a point on a vibrating body or wave determined from its location in equilibrium. The vibration path is equal to one-half the duration.
Frequency- Frequency is the number of events per unit of your time, of a repeated case. It is often referred to as temporal frequency, which underlines the difference between spatial frequency and angular frequency. Frequency is calculated in hertz (Hz) units and is equivalent to one repeat event per second.
Voltage- Voltage is the difference in electric potential between two points, which is defined as the amount of work needed per unit of charge for the test charge to move a test charge between the two points.
Wavelength- Wavelength is the distance between successive points of the similar process on the wave, such as two adjacent crests, troughs or zero crossings, and may also be a function of all travelling waves and are standing waves, like other patterns of spatial waves.
By the definitions it is clear that except voltage every other terms are related to vibration of a body, but the voltage is related to the electric current in a circuit.

So, the correct answer is “Option C”.

Note:
Given all the keywords except voltage all are defined for the vibration in a body, it is defined for any electric circuit the amount of work needed per unit of charge for the test charge to move a test charge between the two points.
