Question

Which of the following set of quantum numbers (ordered n, l, m_l, m_s) are possible for an electron in an atom? -3, 2, 2,-1/2 4, 3, -2,1/2 2,1,0,-1 2,1,0,1/2 2, 2, 2,1/2 3,1,0,-1/2 5, 3, 4,1/2 4, 3, -4, -1/2 Electromagnetic radiation behaves both as particles (called photons) and as waves. Wavelength (A) and frequency (y) are related according to the equation c = lambda x nu where c is the speed of light (3.00 times 10^8 m/s). The energy {E in joules) contained in one quantum of electromagnetic radiation is described by the equation E = hx nu where h is Planck's constant (6.626 times 10^-34 J s). Note that frequency has units of inverse seconds (s^-1), which are more commonly expressed as hertz (Hz). A microwave oven operates at 2.50 GHz. What is the wavelength of the radiation produced by this appliance?

Explanation / Answer

part A

v = frequency = 2.5*10^9 Hz

lambda = wavelength = (3*10^8/(2.5*10^9)) = 0.12 m
