The loudness of sound depends on
$(a)$. its amplitude
$(b)$. its time period
$(c)$. its frequency
$(d)$. its speed

Academic Physics NCERT Class 8

The loudness of a sound depends on its amplitude. the loudness of a sound can be increased or decreased by increasing or decreasing its amlitude.

So, option $(a)$ is correct.

Pitch of sound is determined by its$(a)$. frequency $(b)$. speed$(c)$. amplitude $(d)$. loudness
Order to reduce the loudness of a sound, we have to$(a)$. decrease its frequency of vibration of the sound$(b)$. increase its frequency of vibration of the sound$(c)$. decrease its amplitude of vibration of the sound$(d)$. increase its amplitude of vibration of the sound
The loudness of sound is determined by its$(a)$. amplitude of vibration$(b)$. ratio of amplitude and frequency of vibration$(c)$. frequency of vibration$(d)$. product of amplitude and frequency of vibration
What happens to the loudness of a sound if its amplitude decreases?
When we change a feeble sound to a loud sound, we increase its:(a) frequency (b) amplitude (c) velocity (d) wavelength
Name the characteristic of sound which depends on (a) amplitude (b) frequency, and (c) waveform.
Define amplitude, time period, and frequency of sound wave.
A pendulum oscilliates 18 time in 4 seconds find its time period. And frequency

A pendulum oscillates $40$ times in $4$ seconds. Find its time period and frequency.
Name the unit used to measure the loudness of sound. Also write its symbol.
What happens to the pitch of a sound if its frequency increases?
The magnitude of a current flowing through a device depends(a) only on the voltage across it(b) only on its resistance(c) on its resistance and the voltage across it(d) none of these
The inertia of an object tends to cause an object:$(a)$. to increase its speed$(b)$. to decrease its speed$(c)$. to resist a change in its state of motion$(d)$. to decelerate due to friction
