Electromagnetic Energy and Spectrum

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

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

As the frequency of an electromagnetic wave increases, the amount of energy in that wave...

• increases.
• decreases.
• stays the same.

The height of the wave is known as the _____________.

• amplitude
• crest
• trough
• wavelength

The blue section of the wave is measuring _________________.

• wavelength
• crest
• trough
• amplitude 

What is a photon?

• When radiation burst through electric waves
• The emission of electrons from a metal caused by light striking the metal
• The rate at which a waves energy flows through a given unit of area.
• packets of electromagnetic energy

How are Electromagnetic waves different from Mechanical waves?

• EM waves have very short wavelengths

• EM waves transmit energy instead of matter

• EM waves can travel through the vacuum of space (without particles)

• EM waves can change direction by reflection

Waves are a transfer of what?

• Heat
• Light
• Energy
• Food
