What was the largest wavelength?
As far as visible spectral lines are concerned, red has the largest wavelength. If we consider electromagnetic spectrum, then radio waves could be considered as longer wavelengths. Even longer are long waves.
How are wavelengths of light detected?
Spectroscopy originated through the study of visible light dispersed by a prism according to its wavelength. An instrument called a spectrometer is used in spectroscopy for producing spectral lines and measuring their wavelengths and intensities.
What is spectral energy density?
The energy spectral density describes how the energy (or variance) of a signal or a time series is distributed with frequency.You can read more in Wikipedia 'Spectral Density', but you will need good maths to understand it!
What happen to light as it travels?
As light travels, its wavelength can lengthen or shorten causing it to appear more red the further it travels or more blue if it has traveled a shorter distance. This effect, combined with various chemical spectral identifiers, can be used to determine the distance the light has traveled, giving a rough estimate to the location of its source. changes in wavelength is called redshift(when wavelength is increased) and blueshift(when decreased). redshifts and blueshifts are attributable to the Doppler effect
The Maximum spectral response of the germanium and silicon is in the?
Ultraviolent rays
The spectral lines from distant galaxies do not match spectral lines on Earth due to?
wavelength shift
Parameter which boarding the spectral line?
You think probable to the wavelength.
What is the color of the spectral line with a wavelength of 502 nanometers?
Green.
A spectral line that appears at a wavelength of 321 nm in the laboratory appears at a wavelength of 328 nm in the spectrum of a distant obect we say that the object's spectrum is?
A spectral line that appears at a wavelength of 321 nm in the laboratory appears at a wavelength of 328 nm in the spectrum of a distant object. We say that the object's spectrum is red shifted.
What is a single wavelength of light that can be seen when the light from an excited element is passed through a prism?
A spectral line
What is the Wavelength barium?
Barium has an atomic spectra of lines, not only one line (with one wavelength); I reccomend to consult a catalog of spectral lines. See the link below.
When the wavelength of a spectral line emitted from an object decreaseswhich end of the visible light spectrum does it move towardand what is the objects motion relative to earth?
When the wavelength decreases, that's known as a "blue shift", becausethe color of any visible light shifts toward the blue end of the spectrum.That phenomenon is associated with a light source that's moving TOWARDthe observer.
How would the spectral lines of a star change when moving closer towards earth?
It would change by shifting to the wavelength blue.
How do you calculate the second wavelength in the Paschen series?
Use the Rydberg formula. A useful article about this is on Wikipedia. It is called "Hydrogen spectral series".
How do you use spectral lines to determine if a galaxy is moving towards earth or away from earth?
The spectral lines move towards one direction, or towards the other direction, depending on the relative speed.
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.
