If a wave has a frequency of 6 waves per second and a wavelength of 10 m, what is the wave's speed? A/0.6 m/sec.
B/ 1.6 m/sec.
C/60 m/sec.
D/none of the above​

The nuclear potential that binds protons and neutrons in the nucleus of an atom is often approximated by a square well. imagine a proton conned in an innite square well of length 105 nm, a typical nuclear diameter. calculate the wavelength and energy associated with the photon that is emitted when the proton undergoes a transition from the rst excited state (n 2) to the ground state (n 1). in what region of the electromagnetic spectrum does this wavelength belong?
