The full electromagnetic spectrum (Credit NASA's Imagine the Universe) The spectrum of the Sun appears as a continuous spectrum and is frequently represented as shown below This type of spectrum is called an emission spectrum because what you are seeing is the direct radiation emitted by the source In the case of the Sun, light is emittedThese lines make up the atomic emission spectrum of the atom being studied Each individual line represents a definite wavelength of light emitted by the excited atom The diffraction grating is a device which separates light into a spectrum of its individual wavelengths A prism behaves similarly Gratings are made by etching fine, parallel 2 Answers The Atomic Emission Spectra usefulness can be compared to the usefulness of a fingerprint the atomic emission spectra finger print makes a unique identifier Using this unique identifer, we have found out how hot the stars are, as well as what type of elements were they made of This led to the birth to modern astrophysics

To the best of your knowledge how do you think this emission spectrum is created
To the best of your knowledge how do you think this emission spectrum is created-Alright, so, that energy difference, if you do the calculations, that turns out to be the bluegreen line in your line spectrum So, I'll represent the light emitted like that And, if an electron fell from the 5th energy level down to the 2nd energy level, that corresponds to the blue line that you see on the line spectrum Teach Using the Lived Experiences of Your Students By Rebecca Alber close modal In education, we discuss the importance of using students' prior knowledge What is also important is learning about the "lived experiences" of the children we teach and connecting those experiences to the learning at hand

Chemistry Bohr Model of the Atom Atoms and Electromagnetic Spectra 1 Answer B M It is created when the electrons in an atom return from a higher (excited) state to lowerAn emission line will appear in a spectrum if the source emits specific wavelengths of radiation This emission occurs when an atom, element or molecule in an excited state returns to a configuration of lower energy Since every atom, element and molecule has a unique set of energy levels, the emitted photon ('packet' of radiation) has a discrete wavelength, and an energy equal How an Emission Spectrum Is Produced When an atom or molecule absorbs energy, electrons are bumped into a higher energy state When the electron drops to a lower energy state, a photon is released equal to the energy between the two states What causes the bright lines in the emission spectrum?

Herschel's discovery of emission spectra from heated gas was studied extensively in the 1800's It was realized that a heated gas emits a unique combination of colors, called emission spectrum, depending on its composition Example Helium gas in a discharge lamp Main idea put a large voltage across the gas It will break down and emit light As I say below, an electron cannot be absorbed, which is what I think you are implying above, but a photon, as the force carrier between electrons, can be absorbed and emitted I think there are duplicates for the other related questions in your post, so I And so if you feel like it's going to be successful, that has a little bit to do with selfconfidence, it has a little bit to do with the type of feedback you're getting from the people around you, a little bit to do with whether you've had a mentor who's been there before and says, "Hey, you could do this too" And if we think women may be a little bit less plugged into some of those
