Often asked: 14. Compared To The Sun, A Star Whose Spectrum Peaks In The Infrared Is:?

A star whose spectrum peaks in the infrared is: cooler than our Sun.

Which of the following best describes why the Sun’s spectrum contains 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.

Which forms of light are higher in energy and frequency than the light than our eyes can see?

Human eyes can see things that emit or reflect various colors of visible light. Ultraviolet light has shorter wavelengths and higher energy than visible light. Only extremely hot objects and high-energy events give off X-rays. Once in a while, an explosion on the Sun or in space is energetic enough to emit gamma rays.

How must Star C be different from Star E to account for their difference in energy output explain your reasoning?

Blackbody radiation – How must star C be different from Star E to account for their difference in energy output? Stars C and E both peak at the same wavelength. But the height of the curve at their peak wavelengths (the energy output for each at this peak wavelength) is much greater for Star E than it is for Star C.

What are two ways that the spectrum of an 8000 K star differs from the spectrum of a 4000 K star?

Describe two ways in which the “thermal radiation spectrum” of an 8000 K star would differ from that of a 4000 K star. The 8000 K will have a peak emission wavelength which is shorter (blue) than the 4000 K; according to Wien’s law which says that the peak wavelength is inversely related to the temperature.

How is the spectrum of a hot gas best described?

A hot solid or hot, dense gas produces a continuous spectrum. A continuous spectrum source viewed through a cool, low-density gas produces an absorption-line spectrum.

What type of spectrum does the Sun have?

The full electromagnetic spectrum. 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.

Which wave has the highest frequency?

Gamma rays have the highest energies, the shortest wavelengths, and the highest frequencies. Radio waves, on the other hand, have the lowest energies, longest wavelengths, and lowest frequencies of any type of EM radiation.

Which light has highest energy?

When it comes to visible light, the highest frequency color, which is violet, also has the most energy. The lowest frequency of visible light, which is red, has the least energy.

Which forms of light are lower in energy and frequency than the light?

Which forms of light are lower in energy and frequency than the light that our eyes can see? Infrared and radio.

What is the peak wavelength given off by a hotter star?

The wavelength at which a star emits the most light is called the star’s peak wavelength. The diagram on the right shows that this star has a peak wavelength of 4000 Angstroms.

What occurs as energy is transferred through the convective zone of the sun?

What occurs as energy is transferred through the convective zone of the Sun? Energy is transferred through the large-scale movement of material. Energy is released into the photosphere.

Which statement describe the types of energy emitted by the sun?

All of the energy from the Sun that reaches the Earth arrives as solar radiation, part of a large collection of energy called the electromagnetic radiation spectrum. Solar radiation includes visible light, ultraviolet light, infrared, radio waves, X-rays, and gamma rays. Radiation is one way to transfer heat.

What is a spectrum and how do we see one?

What is a spectrum and how do we see one? A spectrum, more specifically an electromagnetic spectrum, is a scale of wavelengths of different types of light -even those we cannot see. The Visible Light section (which is the only part we can see) is only a tiny, tiny portion of the whole spectrum.

Which spectral lines we see in a star’s spectrum depends in part on the star’s?

The set of spectral lines that we see in a star’s spectrum depends on the star’s: chemical composition.

How do we convert a spectrum shown as a band of light like a rainbow into a graph of the spectrum?

How do we convert a spectrum shown as a band of light (like a rainbow) into a graph of the spectrum? You need to measure the intensity at each position. This can be done with a monochromatic CCD but most spectrographs use photomultiplier tubes for greater accuracy, since it is not necessary to build up an image.
