Waves Unit Test Review

Front

What is amplitude in a wave?

Back

Amplitude is the maximum distance that the particles of a medium move from their rest position when a wave passes through. It is a measure of the wave's energy.

Front

What is wavelength?

Back

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

Front

What is the electromagnetic spectrum?

Back

The electromagnetic spectrum is the range of all types of electromagnetic radiation, which includes radio waves, microwaves, infrared, visible light, ultraviolet, x-rays, and gamma rays.

Front

What are radio waves?

Back

Radio waves are a type of electromagnetic radiation with wavelengths longer than infrared light. They are used for communication, such as in radio and television broadcasts.

Front

What is the difference between transverse and longitudinal waves?

Back

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

Front

What is a medium in the context of wave propagation?

Back

A medium is the substance through which a wave travels, such as air, water, or solid materials.

Front

What is infrared radiation?

Back

Infrared radiation is a type of electromagnetic radiation with wavelengths longer than visible light but shorter than microwaves. It is commonly used in remote controls and thermal imaging.

Front

What is the speed of sound in air?

Back

The speed of sound in air at room temperature is approximately 343 meters per second (1,125 feet per second).

Front

What is the principle of superposition in wave theory?

Back

The principle of superposition states that when two or more waves overlap, the resulting wave displacement is the sum of the individual displacements.

Front

What is constructive interference?

Back

Constructive interference occurs when two waves meet in phase, resulting in a wave of greater amplitude.
