EM Spectrum - Station #3

Drag the different types of waves to the correct position on the EM spectrum as shown.

a

b

c

d

e

f

g

radio

x-ray

UV

IR

microwave

visible

gamma

Label each half of the EM spectrum as either longer or shorter wavelengths.

(hint - check the labels already on the picture!)

b

a

longer wavelengths

shorter wavelengths

Label each half of the EM spectrum as either higher or lower frequencies.

(hint - check the labels already on the picture!)

b

a

lower frequencies

higher frequencies

Select THREE of the EM wave types that are harmful to humans.

(hint - anything with a wavelength smaller than 380 nm can be harmful to humans!)

Match the following real-world examples to each wave type.

Don't forget to write down each example & which type it

belongs to on your EM spectrum in your lab packet!

• gamma rays

• product of radioactive decay, can be used to treat some cancers

• x-rays

• used for medical sanitation, can cause sunburns and provide vitamin D

• visible light

• used for medical imaging, airport security screenings, etc.

• ultraviolet

• made of 7 different colors, used for human vision

Match the following real-world examples to each wave type.

Don't forget to write down each example & which type it

belongs to on your EM spectrum in your lab packet!

• microwaves

• used for radios, cell phones, TV signals, etc.

• radio waves

• used for radar, cooking, and technology communication (like wifi)

• infrared

• used for thermal imaging cameras, heat sensors, and night vision equipment
