100
When you see light bouncing off of a surface, you are seeing light waves being _________
reflected
100
Which color reflects all light?
White
100
The distance between one crest and another
Wavelength
200
Why can't we hear sound in space?
Space is a vacuum/no air
200

The change in direction of light waves or "bending" when they pass through one material to another is
refraction
200
Which type of telescope is pictured below?
Reflecting telescope
200
The top of a wave
Crest or Peak
300
A sound wave is produced by _________ in matter.
Vibrations
300
What happens to sound when it hits brick wall?
It transmits/goes through and gets reflected
300
If a material allows most light that strikes it to pass through but forms a blurry image, then the material is
translucent
300
Which type of Telescope is pictured below?
Refracting Telescope
300
The bottom of the wave
Valley or trough
400
Describe the wavelengths of the sound from object A and how it compares to the sound from object B
A-short wavelengths=high freq.
B-long wavelengths=low freq.
400
What is the definition of an echo?
A reflection of sound
400
Color is arranged by the _________ of visible light.
wavelength or frequency
400
A brick wall does not allow any light to pass through and is therefore __________.
Opaque
400
The height of a wave
Amplitude
500
Which graph is loud and low pitch? Explain your choice using the terms wavelength and amplitude.
Graph B shows a loud and low pitch sound.
-Graph B is showing a loud sound because the height of the waves are tall, which means it has a high amplitude
-Graph B is low pitch because it has longer wavelengths or less waves, which means it has a low pitch.
500
Which state of matter or medium does sound move the slowest?
air or gasses
500
The name for all waves that give off radiation
Electromagnetic Spectrum
500
Which color has the shortest wavelength (ROYGBIV)?
Violet
500
When a sound has short wavelengths, what is another term to describe this
High frequency
