Characteristics of Sound or Light
Light Waves
Rainbow Connections
100
The rapid moving back and forth movement of matter
What is vibration?
100
The way sound and light always travel; disturbances moving through mediums
What are waves?
100
The way light waves travel in straight paths
What are rays?
100
The number of colors in the visible spectrum of white light; (These are the colors in a rainbow.)
What is: 7?
200

Sound travels in this type of wave.

What is compression?

200

The parts of a transverse wave

What are crest & trough?

200

Light travels in this type of wave

What are: transverse waves?

200
An optical device that separates white light into the colors of the visible spectrum
What is a prism?
300

Animals such as bats and dolphins use this to locate food.

What is echolocation?

300
The distance between two compressions of a sound wave
What is a wavelength?
300
1. The quality of most light being able to pass through an object; objects can be clearly seen; 2. Some of the light is able to pass through an object, but it is scattered; objects cannot be clearly seen; 3. None of the light passes through an object
What are: 1. transparent; 2. translucent; 3. opaque?
300
1. This color has the longest wavelength. 2. This color has the shortest wavelength.
What are: 1. red; 2. violet?
400

Sound is an example of this type of energy.

What is: mechanical?

400
This energy is transmitted by vibrating matter; travels in waves that must have a medium in which to move; and travels most quickly through solids.
What is: sound energy?
400

Name three inventions that use reflection of light to work.

What is: a periscope, mirror, sun shield, etc...?

400

The paths light waves travel: 1. until they hit an object; 2. bounce off an object; 3. are bent; 4. pass through an object

What are: 1. absorbed; 2. reflected; 3. refracted; 4. transmitted?

500

What is the relationship between frequency, wavelength, and pitch?

The higher the frequency, the higher the pitch and shorter the wavelength. The lower the frequency, the lower the pitch and lower the wavelength.

500

You can only see objects when this is reflected off the objects.

What is: light?

500

What is the relationship between energy, frequency, and wavelength?

The more energy, the higher the frequency, the shorter the wavelength. The less energy, the lower the frequency, the longer the wavelength.

500
ROY G BIV; The colors of the different wavelengths of visible light
What are: red, orange, yellow, green, blue, indigo, and violet?
