Why the distances between the lines for the hydrogen spectrum decreases with the decrease in wavelength?
Just one line for hydrogen.
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.
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.
Longest wavelength in the spectrum of color?
The color red has the longest wavelength of all the colors in the light spectrum.
In the electromagnetic spectrum is determined by its wavelength?
In the visible spectrum the color is determined by its' wavelength. The energy of the quantum package is determined by the wavelength. The shorter the wavelength the more power per package.
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.
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.
Why the distances between the lines for the hydrogen spectrum decreases with the decrease in wavelength?
Just one line for hydrogen.
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.
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 the best way to determine a galaxy's redshift?
Take a spectrum of the galaxy, and measure the difference in wavelength of spectral lines from the wavelengths of those same lines as measured in the laboratory
What is spectral evidence?
what is spectral evidence Spectrum (spectral) refers to different frequencies of light associated with a substance.

How is color measured?
Color is measured in several ways, including wavelength relative to the light spectrum, intensity, and purity of tone.bright and dark
What is a small point of the electromagnetic spectrum?
In general it can be called a single frequency or a single wavelength. In the infrared, visible, and ultraviolet bands it can be called a spectral line. In the visible band it can be called monochromatic.
What happens when a star's spectrum is redshifted as a result of the Doppler effect?
With respect to light, the Doppler effect refers to the apparent change in the frequency (and wavelength) of electromagnetic radiation due to the relative motion of the source relative to the observer. When the source (i.e. a star) moves AWAY from the observer, there is an apparent rarefaction (expansion) in the wavelength of emitted light (i.e. frequency decreases), causing a shift in the emission spectrum towards the red side. This is known as redshifting --> the star is moving away from the observer. The opposite happens in blueshift, when the source moves towards the observer.
