What is destructive interference?

Back

Destructive interference occurs when two identical waves arrive at the same point exactly out of phase, aligning crest to trough, resulting in a reduction or cancellation of the wave amplitude.

Front

What is a wave?

Back

A wave is a disturbance that moves from its source and carries energy through a medium.

Front

What is wavelength?

Back

Wavelength is the distance between adjacent identical parts of a wave, such as crest to crest or trough to trough.

Front

What is reflection in the context of waves?

Back

Reflection is the change in direction of a wave when it encounters a boundary or a fixed end, causing it to bounce back.

Front

What is a medium in wave propagation?

Back

A medium is the solid, liquid, or gas material through which a wave propagates.

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

What is the period of a wave?

Back

The period is the time it takes for one complete wave cycle to pass a given point, inversely related to frequency.

Front

What is refraction?

Back

Refraction is the bending of a wave as it passes from one medium to another, caused by a change in its speed.

Front

What is diffraction?

Back

Diffraction is the spreading of waves when they encounter an obstacle or pass through an opening.
