Electromagnetic Spectrum (HW 8.1)

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

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

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

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

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

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

Which section of the spectrum is the ONLY one we can see?

• X-rays
• Visible Light
• Gamma Rays
• Ultraviolet Rays

How are electromagnetic waves different from other waves? 

• They have very short wavelengths 
• They transmit energy instead of matter 
• They can travel through empty space
• They can change direction by reflection 

Which of the following electromagnetic waves has the lowest energy?

• gamma ray
• infrared wave
• visible light wave
• microwave

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

• frequency
• amplitud
• wavelength
• hertz

How much of the electromagnetic spectrum is visible?

• All of it
• None of it
• Most of it
• Only a small part
