Understanding Waves and Their Properties

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

The two main types of waves are mechanical waves (which require a medium, like sound waves) and electromagnetic waves (which do not require a medium, like light waves).

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 amplitude?

Back

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

Front

What is the relationship between wavelength and frequency?

Back

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

Front

What is reflection in terms of waves?

Back

Reflection is the bouncing back of a wave when it hits a barrier.

Front

What is refraction?

Back

Refraction is the bending of waves as they pass from one medium to another, changing their speed.

Front

What is diffraction?

Back

Diffraction is the bending of waves around obstacles or through openings.

Front

What are gamma rays?

Back

Gamma rays are a type of electromagnetic radiation with the highest energy and shortest wavelength.
