Electromagnetic Spectrum

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

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

A disturbance in matter that carries energy from one place to another is called a(n):

• Hurricane

• Asteroid Strike

• Mechanical Wave

• Electromagnetic Wave

Which section of the electromagnetic spectrum contains all the colors that we can see?

• Infrared Light

• Visible Light
• Gamma Rays
• Ultraviolet Light

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

• increases.
• decreases.
• stays the same.

The very top of the wave is known as the _____________.

• amplitude
• crest
• trough
• wavelength

The blue bar at the top of the diagram is measuring the wave's  _________________.

• 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

Light behaves like both a particle and a ______.

• Mass
• Wave
• Current

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

• True

• False

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
