Electro Magnetic Spectrum
What is a spectroscope?
A scope that allows you to see the spectrum of colors of an object using visible light.
The two types of optical telescopes.
What are the refracting and reflecting telescopes?
The force that keeps a satellite trapped in orbit around Earth.
What is gravity?
The three types of space probes.
What are the Flyby, Orbiter, and Lander probes?
The action and reaction forces of a rocket.
Action: The engine pushes exhaust gases down.
Reaction: Exhaust gases push the rocket up.
Why do astronomers hope to learn when they use spectroscopes to study stars?
They hope to line up what they see in certain things such as stars, and compare that to certain elements or other properties to see if that could be something making up that star.
The type of optical telescope that uses a convex lens.
What is a refracting telescope?
How can a satellite escape orbit around the Earth?
If it goes too fast.
What makes a space probe different from a satellite?
They aren't trapped in an orbit.
How can you tell which is the action force and what is the reaction force?
Action causes the reaction to happen; without the action happening first, the reaction would never happen.
The type of optical telescope that uses mirrors.
What is a reflecting telescope?
Newton's Law shown with a rocket taking off.
What is the 3rd law?
Why are some telescopes placed in space?
So that they can pick up on radiation of all wavelengths more easily. They can do this better in space because there are no atmospheric gases, the sky is darker, and there is no weather.
