How discharge tube is different from tube light?
discharge tube can be used for indentifying electrons while tube light cxannot
What causes the lines in an atomice spectrum?
wavelengths of absorbed or emitted photons
The light emitted by an incandescent element produces what?
A unique continuous spectrum
Which factor controls the amount of radiation emitted from the xray tube?
mA
Why light emitted by a bulb is yellowish in colour but from a fluroscent tube is white?
You are seeing the spectrum of the metal used in a light bulb. In a florescent tube you are seeing ultraviolet light being transformed into visible light by the internal phosphor coating.
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.
How does an emission spectrum of a gas in a discharge tube differ from a white light spectrum?
It differs by that white light spectrum is continuous and consists of light of all wavelengths. Emission spectrum is not continuous. It consists of bright lines at specific wavelengths, with complete darkness between them.
How discharge tube is different from tube light?

What type of spectrum do most stars have?
The spectrum is a kind of analysis of the light emitted by a star.
Which red line shows the same action spectrum corrected for the unequal number of photons emitted across the visible spectrum?
The red line in the second graph shows the same action spectrum corrected for the unequal number of photons emitted across the visible spectrum.
What is a stellar spectra?
A stellar spectrum is the light emitted by a star.
What is the total collection of photons emitted by a given atom?
Spectrum
What has the author Frank Leigh Robeson written?
Frank Leigh Robeson has written: 'The infra-red spectrum of helium in a long discharge tube ..' -- subject(s): Accessible book, Infrared spectra, Helium 'The infra-red spectrum of helium in long discharge tubes ..' -- subject(s): Helium, Infrared spectra, Spectra
What causes the lines in an atomice spectrum?
wavelengths of absorbed or emitted photons
Which part of electromagnetic spectrum is emitted by warm objects?
IR, mostly.
What does a star emits?
The spectrum is a kind of analysis of the light emitted by a star.
Why crook tube is called discharge tube?
If it's a *Crookes* tube you're asking about, it's a discharge tube because the applied electrical field causes ionization and a resulting discharge of energy in the form (mostly) of light, depending on the gas or gases in the tube.
