Question

A. Choose the correct option
1. Which of the following is false
regarding sound vibrations?
a. The maximum distance by which an
object moves or is displaced from it
mean position is frequency
b. The time taken by the object to
complete one oscillation is called
time period.
c. The total number of oscillations in
one second refers to its amplitude.
d. Frequency of a sound is measured in
decibel (dB).​

Answer 1

Answer:

d) The time taken by the object to complete one oscillation is called time period.

Explanation:

• The maximum distance by which an

object moves or is displaced from it

mean position is its Amplitude not frequency.

• The total number of oscillations in

one second refers to its Frequency not amplitude.

• Frequency of a sound is measured in hertz(Hz) not decibel (dB).

Answer 2

Answer:

the time taken by the object to complete one oscillation is called time period
