LQ: What is the electromagnetic spectrum?

Starter Quiz

This will assess your understanding of the waves topic so far

Multiple Choice

What do waves carry from place to place?

• Ultraviolet Rays

Multiple Choice

These waves from the sun cause sunburn.

• Gamma

• Microwaves

• Radio

Multiple Choice

These waves are used to send signals, including WiFi and text messages.

• Gamma
• Microwaves
• Radio
• Ultraviolet

Multiple Choice

These waves make water molecules vibrate and warm up.

• Gamma
• Microwaves
• Radio
• Ultraviolet

Multiple Choice

Which has the SHORTEST wavelength and, therefore, the highest frequency/most energy

• Radio waves

• Ultraviolet Rays

• Gamma Rays

• X-rays

Multiple Choice

Which has the LONGEST wavelength and, therefore, the lowest frequency/energy

• Gamma Rays
• Radio Waves
• Visible Light
• Infrared rays

Multiple Choice

Select the correct order of waves on the EMS from the longest wavelength to the shortest wavelength

• Radio, Micro, Infra, Visible, Ultra, X-ray, Gamma

• Gamma, X-ray, Ultra, Vis, Infra, Micro, Radio

• Vis, Micro, Infra, Ultra, X-ray, Gamma, Radio

• Micro, Radio, Vis, Infra, Ultra, X-ray, Gamma

Multiple Choice

A wave with a large wavelength will have a ______ frequency and _____ energy

• high, low
• high, high
• low, high
• low, low

Multiple Choice

The energy of waves _______ as the wavelength gets shorter.

• increases
• decreases
• stays the same

Multiple Choice

True or false: as you move along the spectrum, radio to gamma waves, the wavelengths decrease in size (get smaller)

• true

• false
