Sadly, that must depend on where in the metro area your school is located.
In the inner city, the class is most likely to have occasional access to a glass prism
which is passed around to all the classes in that school or all the schools in that district.
In the suburbs and the magnet schools, the class is more likely to have their own
diffraction grating, which the whole class or one of the study groups in it can use
whenever they feel like it.
It is a spectroscope that separates a star's light into color bands. The purpose of this is to assist astronomers in identifying the elements in a star.
A dispersive prism is used to break up light into its constituent spectral colors.

Its elemental composition.
The light spectrum coming from the planet. Each element has its own distinct color spectrum.
Stars and planets are made up of many different atoms. When scientists pass the light coming from the star or planet through the spectrometer they get an emission spectrum. We can compare this emission spectrum to a situation where many people have put their fingerprints in the same spot. The scientist is like a police officer that has to sort them all out. To do this they analyze the emission spectrum to see which atom's individual light fingerprints are in there. In this way, they can use the light from stars and planets to find out what the star or planet is made of.
The hottest stars are white or blue, cooler stars are yellowish. Cooler still are the orange stars. The coolest stars appear red. That's how the spectrum of a star is related to its surface temperature. The reason is that the hotter the star, the shorter the wavelength at which the light is most intense in its spectrum. Blue light is of shorter wavelength than red.
The entire visible spectrum plus the infrared and ultraviolet. They are trying to obscure the stars light and see the faint reflections of any planets nearby.

Light wavelength and light spectrum i believe.
The spectrum is a kind of analysis of the light emitted by a star.
He noted that light emitted from stars is shifted further toward the red of the electromagnetic spectrum . From this he concluded that the universe was expanding.

Spectroscope
light appears it feels really hot because of all the stars and they are very big so that appears and lots of light
The sun's color results from the temperature of its outer layer, which emits light in the yellow part of the visible spectrum. Hotter stars tend to emit more light in the blue part of the spectrum while cooler stars are more reddish.
UV, IR and light WITHIN our visual spectrum are generated by most stars. There are OTHER previously unseen, waves such as Gamma and X-Rays that are also blown out by 'stars', but are not generally referred to as 'light'.
That they were receeding
spectrograph
Yes. Proof: We get heat from the sun and light from a lot of stars.
