1.Answer the following questions

A) Describe how the molecules in a gas produce an emission spectrum. How is this useful in astronomy if we assume that the laws of physics are the same everywhere?

B) Why was the uniform expansion model adopted? How does this lead to a necessary differentiation between classical and cosmological redshift

1) The emission spectrum of a hollow cathode lamp for molybdenum was found to have a sharp peak at 313.3 nm as long as the lamp current was less than 50 mA. At higher currents, however, the peak developed a cup-like crater at its maximum. Explain. 2) Why does the cathode of the hollow cathode lamp have a cylindrical shape? Why is an element lamp required as the source for AA? Which copper line was used for analysis of copper...

1. Fireflies emit light across the visible spectrum, but the peak intensity of their emission is around a wavelength of 550 nm. So let’s make the approximation that all of the light emitted by a firefly has a wavelength of 550 nm. (a) A typical flash of light from a firefly lasts for about 100 ms and has a power of 1.2 mW. How many photons are emitted in each flash. (b) An “electron volt” (eV) is a unit of...

Please answer these three questions (1) In what ways are the photons emitted during stimulated emission related to the incident (stimulating) photons? (2) What conditions must a collection of atoms meet in order to amplify an incident beam of light? (3) Very briefly describe how these requirements are met in a helium
