FREQUENCY OF SOUND

What is Time period

• The loudness of the sound

• The maximum displacement of the bob from the mean position

• The time taken to cover 1 oscillation

• The number of oscillations per second

Give an example of a low pitch sound.

• Chirp of a bird

• Rumble of thunder

• Squeak of a mouse

• Whistle of a tea kettle

The property os sound that varies with change in the frequency of vibration is called _________

• loudness

• pitch

• shear

• anharmonic

If the diagram represents 1 second, what is the frequency?

• 1 Hz

• 2 Hz

• 4 Hz

• 6 Hz

What happens to the frequency of sound when the length of a vibrating string is increased?

• Frequency increases

• Frequency decreases

• Frequency remains the same

• Frequency becomes zero

How does the thickness of a vibrating string affect its frequency?

• Thicker strings produce higher frequencies

• Thicker strings produce lower frequencies

• Thickness has no effect on frequency

• Thicker strings produce frequencies independent of tension
