absorption line

Those are absorption lines for oxygen and water, here, aren't they?

He saw a rainbow of colour, and may even have seen absorption lines.

There were more metal absorption lines than had been shown in the old records.

Then, the star developed many shell absorption lines in its spectrum.

If restricted to absorption lines it would look similar to the illustration (top right).

The spectral absorption lines of water and oxygen were coming from there.

A cut along the spectrum shows the absorption lines of atmospheric oxygen.

When the spectrum is examined, the absorption line features of both stars can be viewed.

There are no absorption lines, just a single hue of brilliant red!"

Sargent was known for his studies of quasar absorption lines.

They weren't able to find the absorption line for NH.

The width of absorption lines may be determined by the spectrometer used to record it.

If has a comparatively long lifetime, then the result will be a transparent window completely inside of the - absorption line.

More extreme frequency-dependence is visible in the absorption lines of cold gases.

Each individual cloud leaves its fingerprint as an absorption line at a different position in the observed spectrum.

The star exhibits spin induced broad absorption lines on its spectrum.

The red shift of the object was determined by analyzing the absorption lines in the quasar light.

Some times this leaves absorption lines in the spectrum we observe from stars beyond the interstellar gas.

These absorption lines are indicators of the chemical composition of the gas.

Then, an absorption line at the given wavelength in a stellar spectrum shows that the element must be present.

Remember those absorption lines I showed you?

This detection helped explain the physical shape of previously poorly understood and related ice absorption lines.

The absorption lines in stellar spectra can be used to determine the chemical composition of the star.

To fully model the photosphere one would need to include every absorption line of every element present.

We picked the operating frequency to coincide with one of the dark absorption lines in the solar spectrum.
