The discovery that white light from stars is a spectrum of colors is attributed to Sir Isaac newton in the late 17th century. He demonstrated this phenomenon through his experiments with prisms, showing that white light can be separated into its constituent colors: red, orange, yellow, green, blue, indigo, and violet. This foundational work laid the groundwork for the field of spectroscopy, which studies the interaction of light with matter.
What else can I help you with?
What appears when colors are absorbed into a stars spectrum?
When colors are absorbed into a star's spectrum, they appear as dark lines or bands called absorption lines. These lines are caused by the specific elements present in the star's atmosphere absorbing certain wavelengths of light, which are then missing from the overall spectrum observed.
What colors are the sun?
The Sun is white hot - the red, yellow, and orange colors come from dust and smog in the air. Compared to other stars, the Sun is slightly in the yellow part of the spectrum, but to us it is white.
How did the sun get its color?
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.
What type of spectrum does the Sun's photosphere produce?
Visible light is a portion of the electromagnetic radiation that is visible to the human eye. Stars Emit their own light. visible Light has a Wavelength of around 80 or 400 nm to about 760 or 780 nm
Why do some stars appear red?
generally speaking things appears the colors that they do because of two things, the way our eyes and brain perceive them and the way the object absorbs and reflects different wavelengths of the light spectrum. our minds interpret the light spectrum as the colors red, orange, yellow, green, blue indigo and violet and any combination of these colors. when light strikes an object, the object absorbs and reflects light waves, for instance if an object appears red to you, it's because the surface of the object absorbs all the other light wavelengths except red, which bounces back to our eye and causes the object to appear red. strangely enough, when all colors of the light spectrum are bounced back to us, we perceive the object to be white and when none of the colors are reflected, we perceive the object to be black!

What can be analyzed by a stars light spectrum?
Its elemental composition.
Why do stars look white in the night sky?
Stars appear white in the night sky because they emit light across a broad spectrum of colors, with a balance of different wavelengths that our eyes perceive as white.
How do scientists determine a stars composition?
Light wavelength and light spectrum i believe.
What are the different colors of all the stars?
Stars can range from blue to red depending on temperature and mass, with yellow stars in the middle and white stars on the back end of the spectrum.
How did the sun get its color?
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.
Which type of spectrum is associated with the radiation of most stars?
Most stars exhibit a continuous spectrum, which contains all wavelengths of light in a continuous distribution. This is often referred to as a blackbody spectrum due to its smooth curve.
What did Hubble conclude when he noted that light emitted from stars is shifting toward the red of the electromagnetic spectrum?
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.
Spectrum light year and parallax?
A light year is how many years it would take light to get to it's destination. Parallax is the few of something in the sky from 2 different angles. Spectrum is the band of colors produced when white light passes through a prism. -popizejones
