1. A particle loses 7.20 x 10-1⁹ J of energy while emitting light. (a) What is the wavelength of the light that is emitted in nm? What portion of the electromagnetic spectrum does this light represent? (b) What is the frequency of the light emitted in sec-¹? (c) If the wave function for an electron has a wavelength of 2 = 500 nm, which would be equivalent to a visible photon if the electron were light instead of a particle, how fast is the electron moving, in m/sec, according to deBroglie's formula?
