Waves Test

Front

What is a wave?

Back

A wave is a disturbance that transfers energy through space or matter, typically characterized by its amplitude, wavelength, frequency, and speed.

Front

What is wavelength?

Back

Wavelength is the distance between two consecutive points of a wave that are in phase, 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 waves that pass a given point in one second, measured in hertz (Hz).

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, calculated as speed = wavelength × frequency.

Front

What are electromagnetic waves?

Back

Electromagnetic waves are waves that can travel through a vacuum and do not require a medium, including radio waves, microwaves, infrared, visible light, ultraviolet, X-rays, and gamma rays.

Front

What is the relationship between wavelength and frequency in electromagnetic waves?

Back

Wavelength and frequency are inversely related; as the wavelength increases, the frequency decreases, and vice versa.

Front

What is the difference between mechanical waves and electromagnetic waves?

Back

Mechanical waves require a medium (solid, liquid, or gas) to travel through, while electromagnetic waves can travel through a vacuum.

Front

What is constructive interference?

Back

Constructive interference occurs when two waves meet and combine to form a wave of greater amplitude.

Front

What is destructive interference?

Back

Destructive interference occurs when two waves meet and combine to form a wave of lesser amplitude or cancel each other out.
