Unreasonable Results A student in a physics laboratory observes a hydrogen spectrum with a diffraction grating for the purpose of measuring the wavelengths of the emitted radiation. In the spectrum, she observes a yellow line and finds its wavelength to be 589 nm. (a) Assuming this is part of the Balmer series, determine ni, the principal quantum number of the initial state. (b) What is unreasonable about this result? (c) Which assumptions are unreasonable or inconsistent?
Show that Stefan’s law results from Planck’s radiation law. Hin: To compute the total power of blackbody radiation emitted across the entire spectrum of wavelengths at a given temperature, integrate Planck’s law over the entire spectrum P(T)=0I(,T)d.

Microscopes are inherently limited in resolution by the wavelength they use. How much smaller detail can be resolved, with an electron microscope that uses electrons that have been accelerated through a potential difference of 20 million volts, than with a visible-light microscope that uses red light, with lambda = 5.0 x 10^-7 m? (Recall that U = qV , where U = electric potential energy, q = electron charge and V = the potential difference.)

1. With what kind of “light” (e-m radiation) can we excite electrons to very high energy states, from which they will fall down in several steps – thereby making a material fluoresce in visible light? a. microwaves. b. sub-millimeter waves. c. radio waves. d. IR. e. UV. 2. Electrons inside elements can be in certain, well-defined excited states (quantum levels). When they leave such a state to a lower energy state, the frequency f of the “light” (electromagnetic radiation) emitted is related to the energy difference ΔE between such two states as: a.an undefined quantity. b. the same as a black-body emitter. c. the same as a gravitational field. d. ΔE = h · f , where h is Planck’s constant. e. related via the equation c = c2 3. About a decade later, using his oil droplet experiment, Millikan was able to find the smallest possible charge on such droplets, which he interpreted as the charge of a single electron. With that and the m/e ratio above, he was…
