Earth science 24.1

What two logical advantages that a radio telescope would have over an optical telescope?

1: the biggest telescope 2: radio wave work day and night

What does our atmosphere do?

Blocks some wave's better than other so we must view them from space- like gamma, x-ray, infrared

List the types of energy that make up the electromagnetic spectrum?

Gamma rays, x-ray, ultra violet light, visible light, infrared radiation, microwaves and radio waves.

What is the particles of lights called?

Photons

How are frequency and wavelength related?

They are inversely related. as wavelength increase frequency decreases as wavelength decrease, frequency increase.

How can you show that visible light is made up of many different wavelength?

You can shine the light through a prism, which will break up the light into different color.

What is the advantage of being a larger telescope?

reflecting because the bigger you can collect more light

What is the blue-shifted?

the blue end of the spectrum, then the object is moving toward us.

What is the red-shifted?

then it must be moving fast, faraway

How is the Doppler effect used in astronomy?

used to be determine weather a star or other body in space is moving away from toward earth.
