Mechanical vs Electromagnetic Waves
Properties of Waves
EM Spectrum
Color
Eyes and sound
100
The high and low points of a wave.
What is crests and troughs?
100
The distance from a crest to the rest position of a wave.
What is amplitude?
100
List the colors of the visible spectrum in order from lowest to highest frequency.
What is ROYGBIV
100
A material reflects all of the light waves that reach is this color.
What is white light?
100
The part of the eye that contains rods and cones?
What is the retina?
200
Sound waves require a medium to travel because they are this type of wave.
What is a mechanical wave?
200
You are creating a wave using a slinky spring. If you start shaking the spring more quickly, the wavelength of the wave will do this.
What is decrease?
200
This part of the EM spectrum transmits heat (thermal) energy.
What is infrared?
200
All of the light that hits an object is absorbed producing this color.
What is black.
200
The pitch of a sound that you hear depends on this characteristic of a sound wave.
What is frequency.
300
Waves that move the particles of the medium perpendicular to the direction that the waves are traveling.
What is transverse waves?
300
The wave that travels faster then anything?
What is light?
300
The form of electromagnetic radiation that has the most energy.
What are gamma rays?
300
A piece of paper appears red through a red filter, green through a green filter, and blue through a blue filter. What color is the paper?
What is white.
300
The part of your eye that sends the message to your brain.
What is the optic nerve?
400
Electromagnetic waves can through these two things.
What is empty space and a medium?
400
The number of wavelengths that pass a point in a certain amount of time.
What is frequency?
400
The wave with the longest wavelength.
What is radio wave?
400
A rainbow of colors appears through a filter due to this.
What is refraction?
400
The order the path of light travels to allow sight to occur as light waves enter the eye.
What is cornea, lens, retina, optic nerve.
500
Waves are created when a source of energy or force causes a medium to do this.
What is vibrate?
500
This increases the loudness of a sound as it increases.
What is amplitude?
500
These wavelengths on the electromagnetic spectrum have shorter wavelengths than visible light.
What are ultra violet, x-ray, and gamma radiation?
500
If a green filter absorbs all colors except green, a blueberry under this green filter would be this color.
What is black?
500
Light must be refracted by these two parts of the eye.
What are cornea and lens?
