Properties of Waves Video

How does a wave typically form in the physical world?

• When energy is created from nothing.

• When a disturbance causes information to move outward from a source.

• When particles spontaneously move in a circular motion.

• When two objects collide and stop moving.

Which of the following correctly defines the amplitude of a wave?

• The distance between two consecutive crests.

• The number of cycles that pass through a given point every second.

• The distance from the peak to the middle of the wave.

• The speed at which the wave travels through a medium.

In which type of wave does the oscillation happen in the same direction as the wave is moving, characterized by compressions and expansions?

• Transverse wave

• Pulse wave

• Continuous wave

• Longitudinal wave

What phenomenon occurs when two waves with the same amplitude but opposite phases (one a crest, one a trough) overlap and cancel each other out?
