Waves Review - 4th

Front

What type of electromagnetic wave has the longest wavelength?

Back

Radio waves have the longest wavelength in the electromagnetic spectrum.

Front

Where is visible light located in the electromagnetic spectrum?

Back

Visible light is located in the middle of the electromagnetic spectrum.

Front

What is the phenomenon called when light changes direction as it passes from air into water?

Back

The phenomenon is called refraction.

Front

What happens to light when it passes from a less dense medium (air) to a denser medium (water)?

Back

The light slows down and bends towards the normal.

Front

Which two waves have the same wavelength when observing multiple waves in the same medium?

Back

Waves A and B have the same wavelength.

Front

What is the electromagnetic spectrum?

Back

The electromagnetic spectrum is the range of all types of electromagnetic radiation, organized by wavelength.

Front

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

Back

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

Front

What type of electromagnetic waves are used for communication?

Back

Radio waves are commonly used for communication.

Front

What happens to the speed of light when it enters a denser medium?

Back

The speed of light decreases when it enters a denser medium.

Front

What is the normal line in the context of refraction?

Back

The normal line is an imaginary line perpendicular to the surface at the point of incidence.
