Waves Basics

Front

What is a wave?

Back

A wave is a disturbance that transfers energy from one place to another without transferring matter.

Front

What is wavelength?

Back

Wavelength is the distance between two consecutive crests or troughs in a wave.

Front

What is frequency?

Back

Frequency is the number of waves that pass a point in one second, measured in Hertz (Hz).

Front

What is the formula to calculate frequency?

Back

Frequency (f) = Speed (v) / Wavelength (λ).

Front

What is amplitude?

Back

Amplitude is the maximum displacement of points on a wave from its rest position.

Front

What is the relationship between amplitude and energy?

Back

The energy of a wave is directly proportional to the square of its amplitude.

Front

What is the speed of a wave?

Back

The speed of a wave is the distance traveled by a wave in a given amount of time.

Front

What is the difference between longitudinal and transverse waves?

Back

In longitudinal waves, particles move parallel to the direction of the wave, while in transverse waves, particles move perpendicular to the direction of the wave.

Front

What is constructive interference?

Back

Constructive interference occurs when two waves meet and their amplitudes add together.

Front

What is destructive interference?

Back

Destructive interference occurs when two waves meet and their amplitudes subtract from each other.
