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
His achievements include improvements to the telescope. Called the "Father of Modern Science."
Who is Galileo Galilei?
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 two main parts of a wavelength
What are crest & trough?
200
The amount of time it takes light from the sun to travel to the Earth
What are: 8 1/2 minutes
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
He investigated the phenomenon of refraction, deducing the wave theory of light, and was the first to suggest that matter expands when heated and that air is made of small particles separated by relatively large distances.
Who is Robert Hook?
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
He is best known for his work on the improvement of the microscope and for his contributions towards the establishment of microbiology. Using his handcrafted microscopes, he was the first to observe and describe single-celled organisms.
Who is Anton van Leeuwenhoek?
400
The paths light waves travel: 1. bounce off an object; 2. are bent.
What are: 1. reflected; 2. refracted
500
The "effect" that describes the change in pitch as the source of a sound moves closer to an object
What is the Doppler effect?
500
You can only see objects when this is reflected off the objects.
What are: 1. (examples of) translucent objects or materials;
2. opaque objects or materials; 3. transparent objects or materials?
500
Considered by many to be the greatest and most influential scientist who ever lived. He built the first practical reflecting telescope[8] and developed a theory of colour based on the observation that a prism decomposes white light into the many colours that form the visible spectrum.
Who is Isaac Newton?
500
If light passes through an object, it is 1.____________. If it does not, it is 2.___________________ as heat.
