A continuous spectrum of a star is a broad range of electromagnetic radiation emitted across all wavelengths. It results from the thermal energy of the star's interior, causing atoms to vibrate and emit photons at various energies. Continuous spectra can be used to determine a star's temperature.

Analysis of the of a star reveals the composition of the star?
That's done by analyzing the star's spectrum.
What is meant by a continuous spectrum?
You can use spectra to estimate the temperature of the star: astronomical thermometer
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.
Dispersing light from a hot wire which emits white light gives what type of spectrum is it?
A hot, glowing wire emits all wavelengths (or colors) of light. This is sometimes called "blackbody radiation." Since all colors are present, you will get a continuous spectrum.
What type of spectrum does a rainbow have?
A rainbow produces a continuous spectrum of colors, known as a continuous spectrum. This spectrum is made up of all the colors of visible light, ranging from red to violet.

That's done by analyzing the star's spectrum.
Does the spectrum of light from a star have no gaps?
The spectrum of light from a star appears continuous, without gaps, because it is a result of the superposition of light emitted at different wavelengths. This continuous spectrum is produced as the star emits light across a range of wavelengths leading to a smooth distribution of colors in the spectrum.

What type of spectrum do most stars have?
Most stars have continuous spectra, which contain a continuous range of wavelengths without any gaps. This is due to the emission of light from the star's surface at various temperatures.
Can a scientist identify a star's composition by looking at its continuous spectrum?
Yes, a scientist can identify a star's composition by analyzing its continuous spectrum. Different elements emit light at specific wavelengths, creating unique spectral lines that can reveal the presence of specific elements in a star's atmosphere. By analyzing these spectral lines, scientists can determine the composition of a star.
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.
Star A emits a continuous spectrum of light that peaks at a wavelength of 450 nm Star B emits a continuous spectrum of light that peaks at a wavelength of 700 nm What is the ratio of the temperature?
Using Wien's displacement law, we can relate the peak wavelength to the temperature of the star. The ratio of their temperatures is approximately 700 nm / 450 nm = 1.56.
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.
Is the continuous spectrum really continuous Or just too close to distinguish?
The spectrum produced by something that's heated, like the sun or an incandescent light, is continuous.
Dispersing light from a hot wire which emits white light gives what type of spectrum is it?
A hot, glowing wire emits all wavelengths (or colors) of light. This is sometimes called "blackbody radiation." Since all colors are present, you will get a continuous spectrum.
Is the spectrum of white light from the sun continuous?
Yes, the spectrum of white light from the sun is continuous, containing all colors of the rainbow. This continuous spectrum is due to the sun emitting light across a wide range of wavelengths.
What type of spectrum can be produced by a solid liquid or a gas?
Continuous spectrum.
