Light and Spectra INTRODUCTION Light and color have intrigued humans since antiquity. In this experiment, you will consider several aspects of light including: a. The visible spectrum of colors (red to violet) b. Bright line spectra as emitted by an excited gas or solid c. The relationship between color, wavelength, fre‑ quency and energy. BACKGROUND AND THEORY Light is a form of energy

hydrogen atom. We can’t see electrons in an atom so we have to study them indirectly. One piece of evidence about the arrangement of electrons is the electromagnetic spectrum. For example, the spectrum of hydrogen is an important piece of evidence that light interacts with matter through the absorption and emission of discrete packets of energy, called quanta. We now call these quanta …

Experiment 9 The Spectrum of the Hydrogen Atom
The Hydrogen Atom– Supplemental Worksheet 1. State the significance of the line spectrum of hydrogen.

Calculate the energy in each of the following spectral transitions in the hydrogen atom. ( ) a. n = 4 n = 1 ( ) b. n = 3 n = 2 ( ) 3
The hydrogen spectrum is an important piece of evidence showing that the electronic structure of the atom is quantized. When an electric discharge is passed through gaseous hydrogen molecule, the hydrogen atoms in the molecule dissociate. This leads to the emission of electromagnetic radiation by the energetically excited hydrogen atoms. The hydrogen emission spectrum consists of radiation …
An atom emits a photon (particle of light) when it “jumps” from a higher state (state with higher energy) to lower and absorbs a photon when it jumps from a lower state to higher. As the energy of a state is discrete, so are the energies associated with these jumps (or transitions).
Remember that the hydrogen spectrum is not a continuous spectrum. It’s a set of discrete lines determined by the changes in energy a hydrogen atom undergoes when exposed to energy.
The spectra of other atoms are not as simple to analyze. Adding just one more proton to the nucleus and one more orbiting electron to the atom for helium results in the com-

Chapter 7 THE HYDROGEN ATOM Atomic Spectra When gaseous hydrogen in a glass tube is excited by a 5000-volt electrical discharge, four lines are observed in the visible
The line emission line spectrum results from electrons dropping from higher energy level to lower energy levels. Each time an electron drops, a proton of light is released whose energy correspond to the difference in energy between the two levels.
In this lab you will measure the wavelengths of four lines in the atomic spectrum of hydrogen. The only lines you will be able to observe are those of the Balmer series, those lines that fall in the visible region of the spectrum (i.e. wavelengths between 400 and 700 nm). The lines of the Balmer series are the lines for which n lower, is equal to 2 (i.e. n L = 2). Other transitions show up in
An average carbon-hydrogen single bond has a bond energy of 414 kJ/mole, an average hydrogen-hydrogen single bond has a bond energy of 435 kJ/mole, and an average oxygen-hydrogen single bond has a bond energy of 464 kJ/mole. Clearly, the electronic energy for hydrogen excitation, as measured spectroscopically, is greater than that of the bonds between a hydrogen atom and any other atom. …

For the hydrogen atom, n. f. is 2, as shown in Equation (1). The reciprocal of the wavelength, 1/λ, is termed the wavenumber, as expressed by Rydberg in his version of the Balmer equation. Niels Bohr used this equation to show that each line in the hydrogen spectrum corresponded to the release of energy by an electron as it passed from a higher to a lower energy level. The physical basis of
