Electromagnetic Spectrum

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

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

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

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

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

• frequency
• amplitud
• wavelength
• hertz

What is the number of waves that pass a point in one second?

• Amplitude
• Frequency
• Period
• Wavelength

The height of the wave from the rest position is known as the _____________.

• amplitude
• crest
• trough
• wavelength

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

• true
• false

High frequency waves have _________ wavelengths.

• varying
• long
• the same
• short

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

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

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

What are electromagnetic waves?

• sound waves
• electric & magnetic fields (energy) that travel through empty space very quickly
• Someone's name
• things like longitudinal waves
