Sample Questions

1multiple correct

Which of the following are characteristics of musical sound? (Select all correct answers)

Show answer

Loudness, Pitch, Quality

The three characteristics of musical sound are: Loudness (related to amplitude), Pitch (related to frequency), and Quality or Timbre (related to waveform).

2multiple correct

Which of the following are examples of free vibrations? (Select all correct answers)

Show answer

Vibrations of a simple pendulum (neglecting air resistance), Vibrations of a tuning fork struck against rubber pad, Vibrations of a loaded spiral spring

Free vibrations occur without external force. Examples include simple pendulum (neglecting resistance), struck tuning fork, and loaded spring. Table vibrations and diaphragm vibrations are forced vibrations.

3multiple choice

SONAR works on the principle of:

Show answer

Reflection of sound

SONAR (Sound Navigation and Ranging) works on the principle of reflection of sound waves. Ultrasonic waves are sent and their echoes are received to determine distance and location of objects.

4multiple choice

Resonance occurs when:

Show answer

Applied frequency equals natural frequency

Resonance occurs when the frequency of the externally applied periodic force matches exactly with the natural frequency of vibration of the body, resulting in maximum amplitude.
