Answer #1

1) The hydrogen bomb is a nuclear weapon that uses a mixture of fission and fusion to produce a massive explosion.

2) A helium–neon laser or HeNe laser, is a type of gas laser whose gain medium consists of a mixture of helium and neon(10:1) inside of a small bore capillary tube, usually excited by a DC electrical discharge. The best-known and most widely used HeNe laser operates at a wavelength of 632.8 nm, in the red part of the visible spectrum

The red HeNe laser wavelength of 633 nm has an actual vacuum wavelength of 632.991 nm, or about 632.816 nm in air.

In this experiment you used the hydrogen spectral lines to calibrate the spectroscope and, with this information, analyzed the helium emission spectrum. Based on your experimental data and the calibration, what is the wavelength of the most energetic photon emitted from helium in the visible region (expressed in nm)?

The ionized helium atom can be treated with a Bohr model with nuclear charge Z=2. The resulting energy levels are four times those of the hydrogen atom: Ehelium=4Ehydrogen= -(54.4eV)/n^2 From those energy levels, calculate the wavelengths of spectral lines from ionized helium for transitions that end on nf=1. Do any of these lie in the visible range? Would any spectral lines of ionized helium lie in the visible range?

1. A diffraction grating is used to separate the spectral lines of light, emanating from a gas discharge tube (e.g., a neon light), that is normally incident on the grating. On a screen placed 2.0 m from the grating, the third-order (m = 3) interference maximum for violet light (λ = 4.4 × 10−7 m) is found to be 0.20 cm farther from the location of the central maximum (m = 0) on the screen than the second-order maximum of...

1. We can observe the wavelengths emitted from Hydrogen. When Hydrogen electrons transition between states, they absorb or emit a particle of light called a photon with energy E=hf. Here f is the frequency of light and h is a constant. a. How much energy does an electron in the n=1 (lowest-energy) state of Hydrogen have? Repeat for n=2 and n=3. b. How much energy is emitted if an electron in the n=3 state transitions to the n=2 state? c....

In the "4p" nuclear fusion reaction 4 nuclei of Hydrogen (i.e. 4 protons) fuse into 1 nucleus of Helium, emitting energy. Describe qualitatively (i.e. in words) the reaction: how is it possible to overcome the electric repulsive force? What is the nuclear force? How is the energy generated?

Red giants derive their energy not from nuclear ructions involving hydrogen, but by reac- tions involving helium. Specifically, a reaction where 3 helium nuclei change into 1 carbon nucleus. The mass of a helium nucleus is 6.645x10-27 kg, and the mass of a carbon nu- cleus is 1.9922x10-26 kg. Use the data to calculate: (1) the mass lost in one such reaction, (2) the energy released in one such reaction, (3) the energy released when a kilogram of helium fuses...

1) When an iron rod is heated to hundreds of degrees Celsius, it begins to glow red. Why does it do this? (Hint: think about Feynman’s “jiggling” atoms, atomic structure, and the nature of light) 2) We saw in lecture that light waves can be polarized. Can sound waves be polarized? If so, give an example of polarized sound. If not, explain why not. 3) Helium-neon lasers emit light with a wavelength of 633 nm (6.33×10−7 m). (a) Is this...

The wavelengths of spectral lines depends to some extent on the mass of the nucleus. This occurs because the nucleus is not an infinitely heavy mass that remains stationary. In fact, in reality, both the nucleus and the electron orbit about their common center of mass. It can be shown that a system of this type is entirely equivalent to a single object with a mass μμ (called the Reduced Mass) that orbits about the location of the nucleus at...

In an experiment we wish to find how many hydrogen atoms in a gas have their electrons ionized (removed). They are accelerated through a 4.50 MV potential and fired in the positive x-direction towards a magnetic field of magnitude B = 0.045 T. The field points out of the plane, in the positive z direction. The field exists from x = 0 to x = 1.00 m. (a) Calculate the y component of an ionized hydrogen atom’s momentum as they...

Consider the following nuclear fussion reaction: 2/1 H + 2/1 H -----> 3/1 H + 1/1 H Each fusion event releases approximately 4.03 MeV of energy. How much total energy, in joules, would be released if all the deuterium atoms in a typical 0.250-kg glass of water were to undergo this fusion reaction? Assume that approximately 0.0115% of all the hydrogen atoms in the water are deuterium. A typical human body metabolizes energy from food at a rate of about...
