Electromagnetic Waves

Infrared rays have a shorter wavelength than

• Ultraviolet ray

• X-rays

• gamma rays

• radio waves

The waves with the longest wavelengths in the electromagnetic spectrum

• Infrared rays

• gamma rays

• radio waves

• X-rays

What happens to frequency when the energy increases?

• it increases

• it stays the same

• it decreases

Which wave has a longer wavelength?

• wave C

• wave D

Which wave has a greater frequency?

• wave B

• wave C

Select the correct order of waves on the EMS from low to high energy

• Radio wave, Microwave, Infrared, Visible, Ultraviolet, X-ray, Gamma

• Visible, Microwave, Infrared, Ultraviolet, X-ray, Gamma, Radio wave

• Gamma, X-ray, Ultraviolet, Visible, Infrared, Microwave, Radio wave

• Microwave, Radio wave, Visible, Infrared, Ultraviolet, X-ray, Gamma

Wavelength and Frequency are related in that...

• they are always the same

• when one increases, the other decreases (inversely proportional)

• there is no correlation

• they both vary in an irregular pattern

The electromagnetic waves with the highest frequencies are called

• radio waves.

• gamma rays.

• X-rays.

• visible light.

In a vacuum, all electromagnetic waves have the same

• wavelength.

• speed.

• frequency.

• amplitude.

Which of the following has frequencies higher than ultraviolet rays?

• visible light
• infrared rays
• x-rays
