Question

One complete to and fro motion of an object is called

• A. wavelength
• B. oscillation
• C. amplitude
• D. frequency

Answer 1

The correct option is B

oscillation

Explanation of correct answer:

(B) oscillation:

1. Oscillation refers to the repeated back and forth movement of something between two positions or states.
2. An oscillation can be a periodic motion that repeats itself in a regular cycle.

Explanation of incorrect answer:

(A) wavelength:

1. The wavelength is the distance covered by the wave during one complete oscillation of the particles of the medium.

(C) Amplitude:

1. The maximum displacement of the particles on either side of the mean position is known as amplitude.

(D) Frequency:

1. The number of complete oscillations made by particles in one second is called the frequency of oscillation.

Hence, option (B) is the correct option.
