What type of spectrum is given off by low-density high temperature gas cloud?
A low-density, high-temperature gas cloud would emit a continuous spectrum. This spectrum shows a broad range of wavelengths without any distinct lines, characteristic of thermal radiation emitted by hot objects.
What is a blackbody spectrum?
A blackbody spectrum is the radiation emitted by an object that absorbs all incoming light and radiates it back. The spectrum shows a continuous range of wavelengths with a characteristic shape that depends only on the object's temperature. This type of spectrum is an idealization used to understand and describe the behavior of objects in thermal equilibrium.
What does the absorption spectrum of an atom show?
The absorption spectrum of an atom shows that the atom emits that spectrum which it absorbs.
What does the p vs t graph reveal about the relationship between pressure and temperature in a system?
The p vs t graph shows how pressure and temperature are related in a system. It helps us understand how changes in temperature affect pressure, and vice versa. The slope of the graph can indicate whether the relationship is direct or inverse.
Why is the suns spectrum and the moon's spectrum the same?
The sun and the moon's spectra are not the same. The Sun's spectrum shows continuous radiation across a range of wavelengths due to its high temperature, while the moon's spectrum shows reflected sunlight with absorption lines due to its lack of inherent light source. They have different compositions and physical properties affecting their spectra.
What are some comparisons with a absorption spectrum and a continuous spectrum?
An absorption spectrum shows dark lines at specific wavelengths where light has been absorbed by a substance. A continuous spectrum shows all colors/wavelengths with no gaps, like the rainbow. The main difference is that the absorption spectrum has specific dark lines while the continuous spectrum is smooth and uninterrupted.
What is the spectrum of Betelgeuse?
The spectrum of Betelgeuse, a red supergiant star in the constellation Orion, is characterized by strong absorption lines indicative of its cooler temperature, which is around 3,500 Kelvin. Its spectrum shows prominent features of elements such as hydrogen, calcium, and titanium, along with molecular bands from titanium oxide (TiO) that contribute to its reddish color. Additionally, Betelgeuse's spectrum reveals signs of variability, likely due to pulsations and mass loss, which can affect the absorption features over time. Overall, the spectrum reflects its classification as a M-type star with distinct characteristics typical of late-type stars.
What can be determined by studying a solar spectrum?
Dark lines of the absorption spectrum give the elemental composition of the chromosphere, information about the magnetic field and density of the surface. The peak of the continuous spectrum gives the surface temperature. The Doppler Effect shows the movement of the sun and the sun's surface. Splitting of spectral lines verifies the magnetism of sunspots.
What are the two types of spectrum?
The two types of spectrum are continuous spectrum, which shows a continuous range of colors with no gaps, and line spectrum, which consists of distinct lines of color separated by gaps.
What kind of spectrum shows all the colors?
a white spectrum because white is made up of all colors.
What is a continues spectrum?
A continuous spectrum shows all of the colors produced when white light passes through a prism.
When a star's spectrum shows dark lines against a continuous background what does this indicate?
Dark lines in a star's spectrum indicate absorption lines, which are caused by elements in the star's atmosphere absorbing specific wavelengths of light. These lines provide information about the composition and temperature of the star.
