What is the continuous spectrum of a star?
A continous spectrum hasn't discrete gaps between lines.
What evidence do you have that the sun contains the element iron?
The spectral lines. Each element has a characteristic "fingerprint" in a spectrum.
What are the characteristics of the spectrum of the cosmic background radiation?
The measurements at a number of discrete frequencies of the background radiation that fills space place their relative amplitudes reasonably close to the curve that characterizes the radiation of a blackbody with a temperature of 2.725 degrees absolute. As such, the peak amplitude is found at the frequency of about 162.5 GHz.
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)
What does the energy of spectral lines represent?
an emission spectrum is produced after atoms are supplied with electrical energy afterwhich they emit energies as they return to ground state after excitement. the emission spectrum is produced with coloured lines on a dark background. these lines all have different wavelengths thus different frequencies and different quantums of energy. each level has a different energy and since these lines show properties of different energies they show also that atoms have discrete energy levels.
What is the continuous spectrum of a star?
A continous spectrum hasn't discrete gaps between lines.
Is the Hg emission spectrum continuous or discrete?
Hg emission is discrete, that's why you can only see certain (discrete) frequencies, as excited electrons fall from one level to another. A heated light bulb, on the other hand, emits a continuous spectrum from all of its variously vibrating charges.
What spectrum is evidence for quantized change?
Line Spectrum
What sort of structure does the spectrum of a pulse train have?
A pulse strain has a structure called a frequency comb. This is a spectrum that has a series of discrete and equally spaced elements.
Can The optical spectrum of hydrogen and all other elements consist of a set of discrete lines?
true
Why is the frequency spectrum of a discrete signal repetitions of the spectrum of the analog signal?
The analog signal is converted to discrete signal. Even after the conversion, the frequency of the actual signal still remains the same. If the frequency of the discrete signal is different from the analog signal, the reconstructed signal would be different again. This is not what we expect. So base spectrum for similar signals have same frequencies, whether they are discrete or analog. Why do the repetitions occur? The original analog signal is multiplied with a dirac pattern. The base frequency is then shifted to the places, where diracs are available. So long the diracs keep repeating, the base frequency do repeats. Hope you are convinced with my answer
Is sawtooth signal analog?
Yes. A signal of plateaus shows quantized or discrete levels of one or the other voltage; only 2 states. A sawtooth signal has a spectrum of states and has many more than 2 discrete states and is thereby analog. A sine wave is also an example of an analog signal - a spectrum of intensity.
What is evidence that a quasar is distant?
a large redshift in the spectrum of the quasar.

Why is the emission spectrum of hydrogen made of discrete wavelengths rather than a continum of wavelengths?
The emission spectrum of all elements is made of discrete wavelengths. Electrons only exist in particular orbitals. They do not spin willy-nilly around the nucleus. If they receive energy, they jump from one orbital to a higher orbital. When they fall back to a lower orbital, they give off a discrete amount amount of energy. That discrete amount of energy comes as the form of light of a particular wavelength. Look at it as an electron having to be on one or another step instead of a ramp. Instead of continually rolling, it goes one step at a time.
What is the evidence for the statement that white light is a composite of all the colors of the spectrum?
Prism
