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
A system of dots and dashes used to communicate
What is Morse Code?
100
The number of colors in the visible spectrum of white light; (These are the colors in a rainbow.)
What is: 7?
200
The number of waves passing a given point in a given time; This determines the pitch of sound.
What is frequency?
200
The parts of a wavelength
What are crest & trough?
200
The amount of time and distance it takes light from the sun to travel to the Earth
What are: 8 1/2 minutes & 150 kilometers?
200
The scientist who invented the electric light bulb
What/who is: Thomas Edison?
200
An optical device that separates white light into the colors of the visible spectrum
What is a prism?
300
The instrument that uses sound waves to locate objects underwater; also the technology that detects the depth, size, and distance of objects underwater by means of sound waves
What is sonar?
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
This scientist discovered that light is made of particles and waves.
What/who is: Albert Einstein?
300
1. This color has the longest wavelength. 2. This color has the shortest wavelength.
What are: 1. red; 2. violet?
400
This determines the pitch of sound.
What is: the frequency of the vibrations?
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
1. A lens that curves inward and makes images appear smaller; 2. A lens that curves outward and makes images appear larger
What are: 1. concave lens; 2. convex lens?
400
The scientist who produced the first pulse of light from a laser beam
What/who is: Robert Maiman?
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. straight; 2. reflected; 3. refracted; 4. transmitted?
500
The apparent change in the pitch of a sound wave, as the source of the sound approaches
What is the Doppler effect?
500
You can only see objects when this is reflected off the objects.
What is: light?
500
1. Wax paper, oil, ice, tissue 2. Brick, science book, wall 3. Window, glass vase, plastic wrap
What are: 1. (examples of) translucent objects or materials; 2. opaque objects or materials; 3. transparent objects or materials?
500
This scientist set up the first central electric power plant.
What/who is: Thomas Edison?
500
ROY G BIV; The colors of the different wavelengths of visible light
What are: red, orange, yellow, green, blue, indigo, and violet?
