Question
The photo shows the Suns visible-light spectrum. Note thatthis spectrum is displayed in many rows so that it fits on thescreen, but in principle it could have been spread out as a single,long band from left to right.
MARK THE CORRECTANSWER
Part A
Which of the following procedures would allow you to make aspectrum of the Sun similar to the one shown, though with lessdetail?
Part B
In the illustration of the solar spectrum, the upper left portionof the spectrum shows the __________ visible light
Part C
Which of the following best describes why the Suns spectrumcontains black lines over an underlying rainbow?
Part D
Part E
Part F
Pass a narrow beam of sunlight through aprism. Take a photograph of the Sun and then useimage-processing software to change the Sun's shape into a long,thin strip. Photograph the Sun through a powerfultelescope. Compare the relative amounts of light that theSun emits as infrared, visible light, and ultraviolet light The photo shows the Sun's visible-light spectrum.

The rainbow colors represent emission byparticular chemical elements, while the black lines represent gapswhere no element can emit light. The Sun produces a continuous rainbow of color,while the black lines are caused by atoms and molecules in Earth'satmosphere. The Sun produces a continuous rainbow of color,while the black lines are caused by imperfections in theinstruments used to record the spectrum. The Sun's hot interior produces acontinuous rainbow of color, but cooler gas at the surface absorbslight at particular wavelengths. Notice that the Sun's spectrum appearsbrightest (or most intense) in the yellow-green region. This facttells us __________. that the Sun should appear yellow-green to oureyes the approximate temperature of the Sun'ssurface the chemical composition of the Sun that the Sun's surface consists of alayer of cooler gas above a hotter interior Suppose we want to know what the Sun is made of. What should we do? Precisely measure the intensity of light ineach of the black lines in the spectrum. Compare the wavelengths of lines in theSun's spectrum to the wavelengths of lines produced bychemical elements in the laboratory. Count the total number of black lines in the Sun's spectrum. Find the precise wavelength at which thebackground rainbow of color peaks in brightness Any spectrum can be displayed either inphotographic form as shown to the left or as a graph. Which of thefollowing graphs could represent a portion of the Sun'svisible light spectrum?
