When the wavelength of spectral lines emitted from an object decreases which end of the visible light spectrum does it move toward and what is the objects motion relative to earth?
When the wavelength of spectral lines emitted from an object decreases, it moves towards the violet end of the visible light spectrum. This is known as a blueshift, indicating that the object emitting the light is moving towards Earth.
When the wavelength of the spectral line emitted from an object decreases which end of the visible light spectrum does it move toward and what is the object's motion relative to Earth?
If the wavelength decreases, the spectral line moves towards the blue end of the visible light spectrum. This phenomenon is known as blue shift, indicating that the object is moving towards Earth.
How are the continuous bright line spectrum and spectral lines similar?
In a continuous spectrum, you see every color in visible light from wavelengths around 380 nm to 780 nm. The bright light spectrum has only light at specific wavelengths, forming narrow regions of lights. This is characteristic of a particular substance, emitting these lights from its unique electron configuration. Light at specific wavelengths is emitted for different substances, but not a continuous rainbow.
What is the difference between absorption and emission spectrum?
Emission spectrum: lines emitted from an atom.Absorption spectrum: absorbed wavelengths of a molecule.
How can a spectroscope be used to identify an element heated to incandescence?
When an element is heated to incandescence, it emits light at specific wavelengths characteristic of that element. A spectroscope can separate these wavelengths, producing a unique spectral pattern called an emission spectrum. By analyzing this spectrum, scientists can identify the element present based on the specific wavelengths of light emitted.
When the wavelength of spectral emitted from an objectincreases which end of the visiblelight spectrum does ti move toward and what is the objects motion relative to earth?
When the wavelength of spectral light emitted from an object increases, it moves towards the red end of the visible light spectrum, also known as the redshift. This indicates that the object is moving away from Earth.
Which physical property of a star does the spectral type measure?
The spectral type of a star measures its surface temperature. This information is derived from the star's spectrum, which shows the distribution of light emitted at different wavelengths. Stars are classified into different spectral types, such as O, B, A, F, G, K, and M, based on their surface temperature and the dominant absorption lines in their spectra.
How long are the wavelengths of radiation emitted by Earth are?
The wavelengths of radiation emitted by Earth are primarily in the infrared spectrum, ranging from about 5 to 100 micrometers. This is known as terrestrial or thermal radiation, and it is a form of heat energy emitted by the Earth's surface and atmosphere.
What is the difference between a continuous spectrum and a line spectrum in terms of the emission of light?
A continuous spectrum shows a wide range of colors emitted by a hot, dense object, while a line spectrum displays only specific colors at distinct wavelengths emitted by atoms or molecules.
What part of the electromagnetic spectrum is most of the suns energy emitted?
Most of the Sun's energy is emitted in the form of visible light. This includes wavelengths from ultraviolet to infrared.
When the wavelength of a spectral line emitted from an object increases which end of the visible light spectrum does not move toward and what is the objects motion relative to earth?
Increasing wavelength is an indication of a Doppler shift caused by an object moving away from the viewer. Longer wavelengths (of the visible spectrum) are redder, shorter wavelengths are bluer. Objects moving away from you have a red shift, objects moving toward you have a blue shift.
What is beryllium spectral lines?
Beryllium spectral lines are specific wavelengths of light emitted or absorbed by beryllium atoms when they undergo transitions between energy levels. These spectral lines are unique to beryllium and can be used in spectroscopic analysis to identify the presence of beryllium in a sample.
