This is typically measured crest-to-crest or trough-to-trough.
What is wavelength?
This wave cannot travel through a vacuum.
What is a mechanical wave?
When light bounces off something.
What is reflection?
The type of light that causes sunburns and skin cancer.
What is ultraviolet (UV) light?
Matter that does not let light pass through.
What is opaque?
This is typically measured midline-to-crest or midline-to-trough.
What is amplitude?
Something all waves do.
What is carry energy?
The phenomena that causes the sky to appear blue.
What is (rayleigh) scattering?
The colors of the visible light spectrum are arranged according to this property.
What is wavelength (or frequency)?
This color of visible light has the shortest wavelength.
What is purple/violet light?
This type of wave moves slowest through solids.
What are light (EM) waves?
Sound waves move fastest through this.
What is a solid?
The phenomena responsible for the bending of light and rainbows.
What is refraction?
This has a higher frequency than x-rays.
What are gamma rays?
The color shirt you should wear to keep cool on a hot day.
What is a white shirt?
A wave that causes the medium to move perpendicular to the direction of the wave.
What is a transverse wave?
A wave that causes the medium to move parallel to the direction of the wave.
What is a longitudinal wave?
A red flower does this to red light.
What is reflect red light?
This type of wave has the longest wavelength, the lowest energy, and the lowest frequency.
What are radio waves?
Based on its interaction with visible light, foggy windows are an example of this.
What is translucent?
A decrease in the density of something, the opposite of compression.
What is rarefaction?
Frequency is measured in this unit.
What is hertz?
When light is taken in by a material and does not bounce back.
What is absorption?
Warm objects like humans emit these.
What are infrared waves?
A word or phrase to describe the relationship between wavelength and frequency.
What is inversely proportional?
