Star spectra - Study guides, Class notes & Summaries

What are the three types of spectra? Correct Answer-Continuous, emission, and absorption spectra What creates a continuous spectrum and what does it look like? Correct Answer-A hot solid, such as a star. All of the color is shown on the spectrum. There are no breaks. What creates an emission line spectrum and what does it look like? Correct Answer-A hot gas, such as a nebula. Only breaks in color are shown. What creates an absorption spectrum and what does it look like? Correct An...

Consider a spectroscopic binary star system in which the spectra of both stars are observed. If Star A is more massive than Star B, which star has the greater orbital velocity? a) Star A b) Star B c) They both have the same velocity d) The star that is closest to the center of mass e) It depends on where they are in their orbits - Consider a spectroscopic binary star system in which the spectra of both stars are observed. If Star A is more massive than Star B, which star has the greater o...

CAPA CH 13 EXAM QUESTIONS AND ANSWERS ALL CORRECT Why is it so difficult to take pictures of extrasolar planets? A) Their light is overwhelmed by the light from their host star. B) Extrasolar planets give off light at different wavelengths than planets in our solar system. C) No telescope is powerful enough to detect the faint light from a distant planet. D) Because they can essentially never be spatially resolved on the images. E) There is too much competition in science that telesco...

astro 3 quizzes 7 & 8Most stars in our galaxy are like this one. Canopus Anilam Betelgeuse Sirius B Barnard's star - correct answer Barnard's star(red dwarfs and MS stars) On a dark night, we can see a range of about 5 magnitudes in brightness between the brightest and faintest stars in the sky. The brightest stars therefore appear about — times brighter than the faintest stars. 2.5 1000 5 100 10 - correct answer 100 Which star is a red giant? Anilam Sirius B Betelgeuse ...

A crescent moon is visible in the northern hemisphere, with the crescent shape on the right side of the Moon. This phase is called: - ️️Waxing crescent A lens ___ light to converge at a point - ️️Refracts A magnetic field line pokes through the Sun's photosphere inhibiting convection and cooling that location. What feature is observed in that location on the photosphere? (Also describe how the other features are formed) - ️️Sunspot A mirror ___ light to converge - ️️Reflects ...

Gizmos Star Spectra Questions and Accurate Answers 2023/2024 What happens when light goes through a prism? - Answer it causes the light to bend (refracts) and separates its light into the different wavelengths. This band of colors is called a spectrum. 2. A rainbow is an example of a spectrum. What is the sequence of colors in a rainbow? - Answer red, orange, yellow, green, blue, indigo and violet 1. On the Star Spectra Gizmo, turn on Show labels. Select star 1 to see its absorption sp...
