WAVES Pacer test review

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 points in phase on a wave, such as crest to crest or trough to trough.

Front

What is the relationship between wavelength and frequency?

Back

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

Front

What is diffraction?

Back

Diffraction is the bending of waves around obstacles or through openings, causing them to spread out.

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 change in direction of a wave as it passes from one medium to another due to a change in speed.

Front

What are electromagnetic waves?

Back

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

Front

What is sound?

Back

Sound is a type of mechanical wave that travels through a medium (solid, liquid, or gas) as a result of vibrations.

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.

Front

What is the principle of superposition?

Back

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