2. Select the arrangement of electromagnetic radiation which starts with the fowest enesty and incteases to greatest enetgy. A) radio, infrared, ultraviolet, gamma rays B) radio, ultraviolet, infrared, gamma rays C) gamma rays, infrared, radio, ultraviolet D) Bamma rays, ultravioiet, infrared, radio E) infrared, ultraviolet, radio, gamma rays. 3. X-rays are produced by bombarding a metal surface with a beam of energetic electrons. If copper is the metil used, the wavelength of the X-radiation is 0.154nm. Calculate the frequency of this radiation. 4. A student uses a microwave oven to heat a meal. The wavelengat of the radiation is 1.20cm. What is the energy one photon of this microwave radiation? 5. Compare the wavelength for an electron (mass =9.111031kg ) traveling at a speed of 1.0107m/s with for a ball (mass =0.10kg) traveling at 35m/s. J F Force x Distance [+]Nm/=1kgm/s2m,1/f/kga2/s2 6. Calculate the de Broglie wavelength of an electron traveling at 1.00N of the speed of light. (The mass of the electron is 9.111011kg and the speed of light is 3.00101m/s ) 7. A hydrogen atom ahsorbs a photon of UV light, and its electron enter the n=4 energy level. Calculate (a) the change in energy of the atom and (b) the wavelength (in nm) of the photon? Hint: lookigg at the Hydrogen atom line spectrum ninad = 1
