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)?

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....

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?

Emission lines from the hydrogen Hβ line (rest wavelength of 486.1 nm) are observed in the spectrum of a spiral galaxy at redshift z = 0.9. The galaxy's disk is observed to be inclined at an angle of 45 degrees to the line of sight. The central wavelength of the line is observed to be shifted by 0.5 nm to the red on one side of the galaxy, and by 0.5 nm to the blue on the other side of...

a) Is it possible to examine the crystal structure using visible light (wavelength between 300 and 700 nm). Why? b) Briefly describe the meaning of the word “optics" in the optical phonon expression. c) What is the effective mass, explain. d) As doped Si:As semiconductor, n, p, and Np means electron, hole and doped (As) respectfully. Use the charge neutrality to determine n/Nd in terms of ni/Nd,for the determination of intrinsic carrier concentration for ni Si semiconductor.
