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 highest to lowest frequency.
What is violet, blue, green, yellow, orange, red.
100
A material reflects all of the light waves that reach it so it is this color.
What is white.
100
The eardrum is sensitive to these two properties of sound vibrations.
What are frequency and amplitude.
200
Sound waves require a medium through which to travel because they are this.
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 transmits heat (thermal) energy.
What is infrared waves.
200
Most of the light that hits a clear window does this.
What is it is transmitted.
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 speed of a wave depends on this.
What is the properties of the medium it travels through.
300
The form of electromagnetic radiation that has the most energy.
What is 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
This property makes sound louder.
What is amplitude?
400
Electromagnetic waves can transfer energy in this.
What is empty space (a vacuum).
400
The number of wavelengths that pass a point in a certain amount of time.
What is frequency.
400
The frequency of a wave is high. What does this mean for the waves' wavelength and energy?
What is the wave has a short wavelength and high energy.
400
Light separates into different colors in a prism because each different frequency of light does this.
What is refracts at a different angle.
400
This increases the pitch of a sound wave.
What is frequency?
500
Some 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 the amplitude of a wave.
500
These portions of the electromagnetic spectrum have a longer wavelength than visible light.
What are infrared, microwave, and radio waves.
500
If a green filter absorbs all colors except green, a blueberry under this green filter would look this color.
What is black.
500
This causes a light to be more bright.
What is amplitude?
