Consider an atom with four (and only four) energy levels.
(a) How many spectral lines will result from all possible transitions among these levels? (How many distinct handshakes can occur within a group of four people?)
(b) Which transition corresponds to the highest-frequency (or lowest-frequency) light emitted?
(c) Suppose that the four energy levels were somehow evenly spaced. How many spectral lines would result?
A particle with a mass of 4.10 × 10-20 kg is oscillating with simple harmonic motion with a period of 2.9 × 10-5 s and a maximum speed of 2.3 × 103 m/s.
A tiny sphere with a charge of q = +6.0 µC is attached to a spring. Two other tiny charged spheres, each with a charge of ?4.0-µC, are placed in the positions, in which b = 3.8 cm. The spring stretches 5.0 cm from its previous equilibrium position..
