This quiz contains 11 questions from a mix of 1 subtopics.
What type of spectrum is emitted by hot objects?
line absorption spectrum
continuous spectrum
line emission spectrum
discrete spectrum
|
How can a continuous spectrum be separated into its component wavelengths?
by passing the light through a prism
by cooling the light to absolute zero
by slowing down the light
by heating the light
|
What is indicated when light from an excited gas passed through a prism shows a line emission spectrum?
the photons have split into their component colors
the photons have combined to form new colors
the gas atoms have emitted photons of particular wavelengths
the gas atoms have absorbed photons of particular wavelengths
|
What does each emission line in the spectrum correspond to?
a forbidden electron transition
a transition between electron energy levels emitting light
the ground state electron transition
a wavelength of infrared light emitted
|
Why does each element have a unique line emission spectrum?
the spectrum combines all colors
each prism splits light differently
each element has unique colors
the electron transitions depend on the element
|
What occurs when white light passes through a gas to produce an absorption spectrum?
atoms in the gas absorb photons of particular wavelengths
electrons in the gas emit photons of particular wavelengths
the gas heats up emitting blackbody radiation
photons combine into white light
|
What process causes the bright lines in an emission spectrum?
absorption of photons by lower energy level electrons
photon decay into lower energy photons
emission of photons by higher energy level electrons
diffuse reflection of photons in the gas
|
What is the name given to a spectrum showing bright lines?
|
What is the name given to a spectrum with dark lines?
|
What optical device separates light into its spectral components?
|
Explain three pieces of information that can be determined from emission and absorption spectra.
