Understanding Waves and Their Properties

What is the main difference between a pulse and a wave?

• A pulse is a continuous disturbance, while a wave is a single disturbance.

• A pulse is a single disturbance, while a wave is a continuous disturbance.

• A pulse and a wave are the same.

• A pulse requires a medium, while a wave does not.

What role does the medium play in wave propagation?

• It moves along with the wave.

• It provides a path for the wave to travel.

• It absorbs the energy of the wave.

• It changes the direction of the wave.

How do waves transfer energy?

• By creating permanent displacement in the medium.

• By oscillating the medium without moving it.

• By transferring matter from one place to another.

• By moving the medium along with them.

What does the term 'phase' refer to in wave motion?

• The position and direction of a vibrating object in its cycle.

• The height of the wave.

• The color of the wave.

• The speed of the wave.

What is the phase difference between two points that are in opposite directions but the same position?

• 90 degrees

• 360 degrees

• 180 degrees

• 0 degrees

What is a wavefront?

• The highest point of a wave.

• A line connecting points of different phases.

• A surface connecting points that are moving at the same phase.

• The lowest point of a wave.

What is true about the direction of wavefronts?

• They are parallel to the direction of wave propagation.

• They are perpendicular to the direction of wave propagation.

• They are random in direction.

• They are at a 45-degree angle to the direction of wave propagation.

What is the definition of wavelength?

• The speed of the wave.

• The height of a wave.

• The time it takes for a wave to complete one cycle.

• The distance between two successive particles in the same phase.

How is wavelength measured?

• From the crest to the trough of a wave.

• From one crest to the next crest.

• From the start to the end of a wave.

• From the highest point to the lowest point of a wave.

What is the relationship between wavefronts and the source of the wave?

• Wavefronts are equidistant from the source.

• Wavefronts are further from the source than any other point.

• Wavefronts are closer to the source than any other point.

• Wavefronts have no relation to the source.
