How does the data from the emmission spectrum provide evidence for discrete energy levels within the atomlevels wirh?
The emission spectrum of an atom consists of distinct lines at specific wavelengths, which correspond to the energy differences between discrete energy levels of electrons within the atom. When an electron transitions from a higher energy level to a lower one, it emits a photon with a specific energy that matches the difference between those two levels. The unique pattern of these emitted wavelengths, or spectral lines, is characteristic of each element, providing strong evidence that electrons occupy defined energy states rather than a continuous range. Thus, the emission spectrum illustrates the quantized nature of atomic energy levels.

What do you call a light spectrum that is not continuous?
A light spectrum that is not continuous is called a discrete or discontinuous spectrum. This means that instead of a smooth progression of colors, there are distinct individual colors or wavelengths present in the spectrum.
What is unique about the spectrum obtained for a fluorescent light?
The spectrum obtained for a fluorescent light is unique in that it produces a discrete line spectrum with distinct peaks at specific wavelengths, rather than a continuous spectrum. This is due to the combination of the phosphor coating in the tube and the mercury vapor emitting specific wavelengths of light when excited.
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?
Sunlight produced spectrum is continuous and contains a broad range of wavelengths, while hydrogen gas produced spectrum consists of discrete lines at specific wavelengths due to the unique energy levels of hydrogen atoms. Sunlight spectrum is continuous due to the various processes that produce light, whereas hydrogen gas spectrum is a result of the energy levels of hydrogen atoms emitting photons of specific wavelengths.
What is the continuous spectrum of a star?
A continuous spectrum of a star is a broad range of electromagnetic radiation emitted across all wavelengths. It results from the thermal energy of the star's interior, causing atoms to vibrate and emit photons at various energies. Continuous spectra can be used to determine a star's temperature.
Does a lightbbulb produce a discrete spectrum?
A lightbulb primarily produces a continuous spectrum rather than a discrete spectrum. This is because it emits light through thermal radiation, where the filament heats up and emits a broad range of wavelengths. In contrast, a discrete spectrum is characteristic of gases or certain materials that emit light at specific wavelengths due to electronic transitions. Therefore, while a lightbulb emits a continuous spectrum, it does not produce a discrete spectrum.
What spectrum is evidence for quantized change?
The electromagnetic spectrum provides evidence for quantized changes in energy levels of atoms. This is seen in the emission or absorption of specific discrete frequencies of light, which is a result of electrons jumping between quantized energy levels within the atom. This phenomenon is described by quantum mechanics.
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 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
What do you call a light spectrum that is not continuous?
A light spectrum that is not continuous is called a discrete or discontinuous spectrum. This means that instead of a smooth progression of colors, there are distinct individual colors or wavelengths present in the spectrum.
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.
