Can you hear me?
This sense is only possible because of sound waves.
Hearing
A wave bouncing off an object.
Reflection
The height of a wave.
Amplitude
This color of visible light has the longest wavelength.
Red
These waves let us see our bones.
X-rays
Sound requires this in order to travel.
Matter/Molecules/Atoms
This kind of wave moves fastest in dense materials.
Sound Waves
The distance between one point on a wave and the closest similar point.
Wavelength
The kind of electromagnetic wave that is the most damaging to humans.
Gamma Rays
These waves aid us with wireless communication and warming up last night's leftovers.
Microwaves
Sound is unable to pass through this medium.
Space/Vacuum
Waves converting into thermal energy when striking an object.
Absorption
How often a wave passes the resting position in a given time frame.
Frequency
The effect which happens when light changes speed between mediums.
Refraction
Electromagnetic waves commonly used to sterilize food and water.
Ultraviolet
Sound travels fastest in this state of matter.
Solids
This type of wave can travel in the vacuum of space.
Light/Electromagnetic waves.
The distance between a crest and a trough.
Twice/Double the amplitude
The color an orange shirt would appear under only blue light.
Black
Gamma rays are used to treat this disease.
Cancer
This natural disaster is nothing more than massive sound waves moving through Earth.
Earthquakes
Light scattering off a rough surface produces this kind of reflection.
Diffuse
Waves with more energy have a higher number of these two components.
Amplitude and frequency
This kind of electromagnetic wave is also known as thermal radiation.
Infrared
This color stays cooler in the sun because it reflects every wavelength of light.
