COMP 2: Waves & The Sun

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, ordered by wavelength.

Front

What is the order of the electromagnetic spectrum from shortest to longest wavelength?

Back

Gamma rays, X-rays, Ultraviolet, Visible Light, Infrared, Microwave, Radio.

Front

What is a mechanical wave?

Back

A mechanical wave is a wave that requires a medium (solid, liquid, or gas) to travel through.

Front

What is an electromagnetic wave?

Back

An electromagnetic wave is a wave that can travel through a vacuum and does not require a medium.

Front

How does frequency relate to wavelength in waves?

Back

As the frequency of a wave increases, its wavelength decreases, and vice versa.

Front

What is the relationship between energy and frequency in electromagnetic waves?

Back

Higher frequency electromagnetic waves carry more energy than lower frequency waves.

Front

What type of wave is sound?

Back

Sound is a mechanical wave because it requires a medium (like air or water) to travel.

Front

What type of wave is light?

Back

Light is an electromagnetic wave because it can travel through a vacuum.

Front

What is the speed of electromagnetic waves in a vacuum?

Back

The speed of electromagnetic waves in a vacuum is approximately 299,792 kilometers per second (or about 300,000 km/s).

Front

Which electromagnetic wave has the least energy?

Back

Radio waves have the least energy among the electromagnetic waves.
