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 else can I help you with?
What transition in the hydrogen spectrum would have the same wavelenght as the balmer transition n4 to n2 of he spectrum?
The Balmer transition from ( n=4 ) to ( n=2 ) in the hydrogen spectrum corresponds to a wavelength of approximately 486 nm. The transition in the hydrogen spectrum that would have the same wavelength is the transition from ( n=5 ) to ( n=3 ), which also produces a spectral line at around the same wavelength. Both transitions can be calculated using the Rydberg formula for hydrogen spectral lines.
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.
Which rays have the longest wavelength in the visible light?
That's the last color you can see on the redendof the rainbow or other spectral display. It's notexactly the same for all eyes.
Why the positions of the spectral lines of barnard's star are all shifted toward the blue end of the spectrum?
The spectral lines of Barnard's Star are shifted toward the blue end of the spectrum due to the Doppler effect, indicating that the star is moving towards us. This blue shift occurs because the wavelengths of the light emitted by the star are compressed as it approaches, resulting in higher frequency and shorter wavelength light. This motion can be attributed to the star's proper motion relative to Earth. Such shifts are crucial for astronomers to understand stellar dynamics and distances.
How does radiation change across the electromagnetic spectrum?
Radiation changes across the electromagnetic spectrum based on the wavelength and frequency of the electromagnetic waves. As you move from radio waves to gamma rays, the wavelength decreases and the frequency increases. This results in higher energy levels and greater potential for ionization as you move towards the gamma ray end of the spectrum.
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.
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.
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.
As the wavelength of a wave increases on the electromagnetic spectrum what happens to the energy of the wave?
As a wavelength increases in size, its frequency and energy (E) decrease.
How are frequency and wavelength related for the spesific region of the spectrum?
In the electromagnetic spectrum, frequency and wavelength are inversely related. As frequency increases, wavelength decreases, and vice versa. This means that in a specific region of the spectrum, if one parameter increases, the other must decrease to maintain the constant speed of light.
What transition in the hydrogen spectrum would have the same wavelenght as the balmer transition n4 to n2 of he spectrum?
The Balmer transition from ( n=4 ) to ( n=2 ) in the hydrogen spectrum corresponds to a wavelength of approximately 486 nm. The transition in the hydrogen spectrum that would have the same wavelength is the transition from ( n=5 ) to ( n=3 ), which also produces a spectral line at around the same wavelength.

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 radio wave's relative wavelength and frequency compared to other waves in the Electro-Magnetic Spectrum?
Radio waves are the lowest frequency (and therefore longest wavelength) waves in the electromagnetic spectrum.
What is the name of a color determined by its position in the spectrum?
The name of a color determined by its position in the spectrum is called a spectral color. These colors are typically seen in a rainbow and are produced by a single wavelength of light.
What is the second longest wavelength in the absorption spectrum of hydrogen?
The second longest wavelength in the absorption spectrum of hydrogen corresponds to the transition from the n=2 to n=4 energy levels. This transition produces a spectral line known as the H-alpha line, which falls in the red part of the visible spectrum at a wavelength of 656.3 nm.
What 2 properties of EM waves change from one end of the EM spectrum to the other?
Two properties of electromagnetic waves that change across the spectrum are wavelength and frequency. As you move from one end of the spectrum to the other, the wavelength decreases and the frequency increases.
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.
