Question

What is the relation between sound produced by an object and its (a) Frequency (b) Pitch (c) Amplitude​

Answer 1

Answer:

(A) Loudness is determined by the amplitude of the sound wave which in turn depends on the force with which the object is made to vibrate. (B) Pitch of a sound is determined by its frequency. (Apart from this, the pitch of sound also depends upon the relative motion between the source of sound and the listener).

hope it helps!!if so mark the brainliest

Answer 2

Option a is correct

Frequency

• The vibrations of things create sound, which is transported across a medium from one spot to another.
• Vibration is the to-and-fro or back-and-forth motion of an item.
• Vibrations are caused by items moving. We can sense vibrations with our naked eyes in many circumstances.
• While their amplitude is sometimes so little that we cannot see it, we may feel it. The amplitude of a sound determines its loudness.
