Oscillation and Waves Quiz

For an object to oscillate with SHM, the restoring force must be:

• Constant

• Proportional to displacement and in the opposite direction

• Proportional to the square of the displacement

• Zero

In a simple pendulum, the restoring force is provided by:

• Tension in the string

• Gravity

• Air resistance

• Inertia

The time period of a simple pendulum depends on:

• Mass of the bob

• Length of the pendulum

• Amplitude of oscillation

• Both a & b

If the length of a pendulum is quadrupled, its time period becomes:

• Halved

• Doubled

• Four times

• Unchanged

Damping in SHM means:

• Increase in amplitude

• Decrease in amplitude

• Constant amplitude

• No oscillation

Waves transfer:

• Matter

• Energy

• Both matter and energy

• Neither matter nor energy

Which of the following is NOT a mechanical wave?

• Sound wave

• Light wave

• Water wave

• Wave on a string

Electromagnetic waves can travel through:

• Vacuum

• Solids

• Liquids

• All of the above

In a transverse wave, particles vibrate:

• Parallel to wave direction

• Perpendicular to wave direction

• At an angle of 45 degrees

• In a circular motion

In a longitudinal wave, particles vibrate:

• Parallel to wave direction

• Perpendicular to wave direction

• At an angle of 45 degrees

• In a circular motion
