1. (a) Use Rydberg formula to calculate the wavelengths of the four visible lines in the Balmer series of light emitted by a hydrogen gas-discharge lamp. A diffraction grating of width 1 cm has 2500 slits. It is used to measure the wavelengths of the visible spectrum of hydrogen.

(b) Determine the first-order diffraction angles of the four observed lines.

(c) What is the angular width of each one of them?

For wavelengths of two lines in a vacuum measuring 3033.71 and 3033.75 angstroms. (a) Calculate the frequency for both wavelengths (b) calculate the index of refraction for air (at the frequency of the lower wavelength. (c) A light source emits only at the lower wavelength (3033.71 angstroms) and is directed into a Michelson interferometer. If the moving mirror in the interferometer travels at a velocity of 0.15cm/sec and moves a total distance of 0.40 cm what would the resulting interferogram...

The only visible spectral lines of hydrogen are the four Balmer series lines (transitions to n=2). We wish to cause hydrogen gas to glow with all its characteristic visible colors. a) To how high an energy level must the electrons be excited? b) Energy is absorbed in collisions with other particles. Assume that after absorbing energy in one collision, an electron jumps down through lower levels so rapidly so that it is in the ground state before the collision occurs....

Calculate the wavelength difference between the second lines in the visible regions of the hydrogen spectra of (Deuterium) and (Tritium) isotopes. (mass of deuterium and tritium nuclei is approximately 2 and 3 times the mass of hydrogen nuclei, respectively. mass of the hydrogen nucleus is also 1836 times mass of the electron)?

4. The Balmer Series The Balmer series is limited to wavelengths in the visible regions from 250 nm to 700 nm. On the basis of your entries in the above table and the transitions on your energy level diagram what common characteristic do the lines in the Balmer series have? What would be the shortest and longest possible wavelengths for a line in the Balmer series?

What visible wavelengths of light are strongly reflected from a 390-nm-thick soap bubble?

A soap bubble is essentially a thin film of water surrounded by air. The colors you see in soap bubbles are produced by interference. What visible wavelengths of light are strongly reflected from a 390-nm-thick soap bubble? What color would such a soap bubble appear to be?

three of the strongest lines in the He+ ion spectrum are observed at the following wavelengths: (1) 121.57 nm (2) 164.12 nm (3) 25.64 nm. Find the quantum numbers of the initial and final states for the transitions that give rise to the these three lines. Use equation 4, the wavelengths of lines that can originate from transitions involving any two of the four lowest levels. Equation 4: delta E = E(upper) - E(lower) = (1.119627 x 10^5 kJ/mole) /...
