Waves

Front

What is a wave?

Back

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

Front

What are the two main types of waves?

Back

Mechanical waves and electromagnetic waves.

Front

What is the difference between mechanical and electromagnetic waves?

Back

Mechanical waves require a medium (like air or water) to travel through, while electromagnetic waves do not require a medium and can travel through a vacuum.

Front

What is amplitude in the context of waves?

Back

Amplitude is the maximum height of a wave from its rest position, indicating the energy of the wave.

Front

What is wavelength?

Back

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

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 relationship between frequency and wavelength?

Back

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

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 type of electromagnetic wave is used in microwave ovens?

Back

Microwaves.

Front

Which electromagnetic wave has the highest frequency?

Back

Gamma rays.
