Wave Interference

Front

What is wave interference?

Back

Wave interference is the phenomenon that occurs when two or more waves overlap and combine to form a new wave pattern.

Front

What are the two main types of wave interference?

Back

The two main types of wave interference are constructive interference and destructive interference.

Front

Define constructive interference.

Back

Constructive interference occurs when two waves meet in phase, resulting in a wave of greater amplitude.

Front

Define destructive interference.

Back

Destructive interference occurs when two waves meet out of phase, resulting in a wave of lesser amplitude.

Front

What is a medium in the context of wave propagation?

Back

A medium is a substance through which a wave can travel, such as air, water, or solid materials.

Front

What is the difference between mechanical and electromagnetic waves?

Back

Mechanical waves require a medium to travel through, while electromagnetic waves do not and can travel through a vacuum.

Front

What is wavelength?

Back

Wavelength is the distance between two consecutive points in phase on a wave, such as crest to crest or trough to trough.

Front

What is amplitude?

Back

Amplitude is the maximum displacement of points on a wave from its rest position, indicating the wave's energy.

Front

What is frequency?

Back

Frequency is the number of complete wave cycles that pass a given point in one second, measured in hertz (Hz).

Front

How does frequency relate to pitch in sound waves?

Back

Higher frequency sound waves produce higher pitch sounds, while lower frequency sound waves produce lower pitch sounds.
