The spectrum of the Sun appears as a continuous spectrum and is frequently represented as shown below. This type of spectrum is called an emission spectrum because what you are seeing is the direct radiation emitted by the source.
What kind of spectrum does the Sun have quizlet?
-The Sun’s spectrum is an absorption line spectrum , which is produced when continuous light from a hot source (the Sun’s interior) passes through a cooler cloud of gas (the gas that makes up the Sun’s visible surface).
What is the spectrum of the Sun?
The spectrum starts with red light, with a wavelength of 700 nanometers (7,000 angstroms), at the top. It spans the range of visible light colors , including orange and yellow and green, and ends at the bottom with blue and violet colors with a wavelength of 400 nm (4,000 angstroms).
Why does sunlight produce a continuous spectrum?
stars and stellar spectra
The continuous (as distinct from the line) spectrum of the Sun is produced primarily by the photodissociation of negatively charged hydrogen ions (H − ) —i.e., atoms of hydrogen to which an extra electron is loosely attached.
Does sunlight produce a line spectrum?
The Sun produces an absorption spectrum, with dark lines across its spectrum . Chemical elements in the Sun’s corona absorb specific wavelengths of light so their electrons are excited to higher energy levels.
Why does the Sun’s spectrum contain black lines over an underlying rainbow?
Which of the following best describes why the Sun’s spectrum contains black lines over an underlying rainbow? The Sun’s hot interior produces a continuous rainbow of color , but cooler gas at the surface absorbs light at particular wavelengths.
Why is a sunflower yellow quizlet?
why is a sunflower yellow? It reflects yellow light . ... matter can emit light, absorb light, transmit, and scatter (reflect) light.
What are 4 types of radiation from the Sun?
Solar radiation includes visible light, ultraviolet light, infrared, radio waves, X-rays, and gamma rays .
What are the 3 types of spectrums?
- Continuous spectrum.
- Line spectrum and.
- Band spectrum.
How many lumens does the Sun produce?
For every watt our sun puts out, it produces 93 lumens of visible light. So at earth’s orbit, for each square meter, our sun puts out 127,000 lumens. That is very bright.
Is the spectrum of the sun continuous?
The full electromagnetic spectrum. The spectrum of the Sun appears as a continuous spectrum and is frequently represented as shown below. ... In the case of the Sun, light is emitted at almost all energies in the visible spectrum, which is why you see all of the colors in the Sun’s spectrum.
What does a continuous spectrum do?
A spectrum has three components: the continuum, absorption lines, and emission lines. Continuous spectra (also called thermal or blackbody spectra) arise from dense gases or solid objects which radiate heat . They emit radiation over a broad range of wavelengths, thus the spectra appear smooth and continuous.
What is the difference between a continuous spectrum and line spectrum?
There is a continuous and line spectrum. A continuous spectrum consists of all wavelengths within a certain range . This spectrum looks like a rainbow. In contrast, a line spectrum only consists of a few wavelengths.
Who first used a glass prism to obtain the sun’s spectrum?
EXPLANATION: From the above, it is clear that Issac Newton was the first to use a glass prism to obtain the spectrum of sunlight.
Why does an atom give line spectrum?
atoms is known as a line spectrum, because the radiation (light) emitted consists of a series of sharp lines . The wavelengths of the lines are characteristic of the element and may form extremely complex patterns.
What colors of light are in sunlight?
The entire spectrum of visible light emitted by the sun can best be seen through a prism. With a prism, sunlight can be broken down into its components – red, orange, yellow, green, blue, indigo and violet . These colors, from violet to red, are abbreviated as VIBGYOR.
