Electromagnetic Spectrum

The full range of frequencies of electromagnetic radiation is called

• visible light.

• radio waves.

• the electromagnetic spectrum.

• invisible radiation.

Visible light is closest to which two waves types on the spectrum?

• radio waves and X-rays.

• microwaves waves and infrared waves

• infrared waves and ultraviolet waves

• radio waves and gamma rays.

Newton’s prism experiments showed that white sunlight is made up of

• the full electromagnetic spectrum.

• only blue light.

• all the colors of the visible spectrum.

• only the longest wavelengths.

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

• true
• false

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

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

This type of EM wave can cause skin cancer. 

• microwaves
• ultraviolet ray
• radio
• infrared

________ is an EM wave that has the LEAST energy.

• radio
• gamma rays
• microwaves
• visible light

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

• Radio waves
• Ultraviolet Rays
• Gamma Rays
• X-rays

The distance between two crests or two troughs of a wave is called:

• frequency
• amplitud
• wavelength
• hertz

Select the correct order of waves on the EMS 

• 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
