Unit 3 Waves Review

Front

What is the definition of frequency in the context of waves?

Back

Frequency is the number of wavelengths that pass a point each second.

Front

What are mechanical waves?

Back

Mechanical waves are waves that require a medium (solid, liquid, or gas) to travel through.

Front

What causes light to refract when a rainbow is formed?

Back

Light refracts due to small raindrops in the atmosphere.

Front

What do radio waves, microwaves, X-rays, and gamma rays have in common?

Back

They are all types of electromagnetic waves.

Front

What is a transverse wave?

Back

A transverse wave is a wave in which the motion of the medium is perpendicular to the direction of the wave's travel.

Front

What is the relationship between wavelength and frequency?

Back

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

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 is the difference between longitudinal and transverse waves?

Back

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

Front

What is an example of a mechanical wave?

Back

Sound waves are an example of mechanical waves.

Front

What is the electromagnetic spectrum?

Back

The electromagnetic spectrum is the range of all types of electromagnetic radiation, from radio waves to gamma rays.
