Who discovered the dark line spectrum?
Lippershey first discovered a dark-line spectrum.
Is an absorption spectrum also called a bright line spectrum?
No, its an absorption spectrum
How do we see luminous objects?
We can see non-luminous objects because the light reflect off the object and into our eyes that's why at night you can only see a faint out line of the objects around you
What kind of spectrum do dark lines appear against a bright a bright background of colors ranging from red to blue?
Dark-line spectrum is a "photo-negative" of emission spectrum. It is the gaps that appear in precisely the same location as corresponding bright lines. produced by a cool gas with a hot solid and you
How does the intensity of a spectral line yield information about the source of the light?
Intensity of spectral line show the abundance of different elements in the light source. Every element has its own "fingerprint" which can indicate its presence.
What are two examples of a luminous source that produces a line spectrum?
1. Glow discharge lamp 2. Electrode discharge in spectrometry
What does the term bright line spectrum mean?
There are several kinds of spectra. Bright line spectrum, or emission spectrum, is when light emitted by a gas has an electrical discharge going through it, and it produces a spectrum of just a few isolated parallel lines.
Who discovered the dark line spectrum?
Lippershey first discovered a dark-line spectrum.
What spectrum is evidence for quantized change?
Line Spectrum
Is an absorption spectrum also called a bright line spectrum?
No, its an absorption spectrum
What were dark lines in the spectrum named for?
Dark lines especially in solar spectrum have been named as Fraunhofer lines. These line are good examples for line absorption spectrum
Continuous spectrum with dark lines where light is absorbed?
dark-line spectrum...
Why atom gives the line spectrum and molecule give the band spectrum?
atom give line spectrum because it is sharukh khan and molecule is salman khan that is why it give continiuos spectrum
How do we see non -luminous objects?
We can see non-luminous objects because the light reflect off the object and into our eyes that's why at night you can only see a faint out line of the objects around you
What is the difference between sunlight produced spectrum and hydrogen gas produced spectrum?
The spectrum of sunlight is continuous while for hydrogen is line spectrum (discontinuous)
Is an atomic emission spectrum a continuous range of colors?
No. Atomic emission spectrum is non-contiuous and it is named as line spectrum.
What Causes a line in a line spectrum?
Wavelengths of absorbed or emitted photons Every line in a line spectrum is caused by a transition, from one quantum state to another quantum state, involving electrons.
