a
The visible spectrum is part of the electromagnetic spectrum that is highlighted in all spectrum diagrams
b
The visible spectrum is part of the electromagnetic spectrum that does not contain any colors at all
c
The visible spectrum is part of the electromagnetic spectrum has the highest wavelength of all forms of light
d
The visible spectrum is the part of the electromagnetic spectrum that can be seen by human eyes
Question 4 (1 point)
Which of the following would be an example of non-visible light?

a
Radio
b
Infrared
c
Ultra-Violet
d
All of the above
Question 5 (1 point)
Look at the following picture of a gas in a canister exposed to mutliple wavelengths of light

Which of the following statements is most accurate about the gas?

a
The gas does not absorb any light
b
The gas absorbs light with a wavelength that corresponds to the color green
c
The gas reflects the light that enters it
d
The different colors of the light do not merge in the gas and instead, the gas keeps them separated
Question 6 (1 point)
The most abundant element in all stars is

a
Hydrogen
b
Helium
c
Iron
d
Carbon




This chart above is an example of emission and absorption spectra.

Every element absorbs and emits specific colors of light. So when you have an emission spectra or absorption spectra pattern, you can identify the elements that make up the object giving off those colors of light.

By looking at the light coming from an object, you can determine the materials that make it up. This analysis is called Spectroscopy.

Question 7 (1 point)
Why can stars not be categorized by simply comparing their brightness?

a
Most stars are too far away to be seen from Earth
b
Most stars are moving too quickly to be categorized from Earth
c
Most stars seem equally bright from Earth
d
Most stars are too dim in order to be able to tell the difference between them from Earth
Question 8 (1 point)
Since we cannot classify stars by brightness, what are stars actually classifed by?

a
Temperature and Color
b
Brightness and Color
c
Chemical Make up and Temperature
d
Color and Distance from the Earth
This is a star classification chart by temperature and color



The color of the star depends on the temperature of the star. Scientists can estimate the temperature of a star by its color. They label the different stars by color and temperature.



Our own Sun is classified as a "G-Class" star, due to it's yellowish color.

In terms of size, our Sun is only medium sized when compared to other stars in the Universe

a
Nuclear Fusion
b
Nuclear Fission
c
Nuclear Electromagnetism
d
Nuclear Radiation

This image is of what is called the 'birthplace of stars'

What is this place called?

a
Corona
b
Nebula
c

A star's life cycle is measured by

a
The amount of hydrogen fuel is still has left
b
The current color of the star
c
The temporary location of the star
d
The number of heavier atoms produced by the star
