Question 1 1 pts Comparing photons of different wavelength, choose the correct statement. 0 Photons with shorter wavelength and photons with longer wavelength have the same energy. 0 Photons do not have denite energies. O Photons with shorter wavelength have smaller energy than photons with longer wavelength. 0 Photons with shorter wavelength have larger energy than photons with longer wavelength. Question 2 1 pts Comparing two photons with different energy in vacuum. choose the correct statement 0 The photon with larger energy has larger frequency. 0 The photon with larger energy has longer wavelength. 0 The photon with larger energy has larger amplitude. O The photon with larger energy has larger speed. Question 3 1 pts An electron is in the second excited state in = 3) of an atom. Which shell is it in? O Kshell O l. shell 0 M shell 0 N shell D Question 4 1 pts Choose the correct statement about characteristic X-rays. O Characteristic X-rays are produced when electron in lower orbitals move up to higher orbitals. O Different elements have characteristic X-rays at different photon wavelength. O Characteristic X-rays are produced when Compton scattering occurs. O Characteristic X-rays always have the same wavelength regardless of the choice of elements. D Question 5 1 pts X-rays are attenuated by Compton effect. Choose the correct statement. O The incident X-ray photons are completely absorbed to excite the electrons in a lower orbital to a higher orbital, and no electron is ejected. O The incident X-ray photons are partially absorbed to excite the electrons in a lower orbital to a higher orbital. No electron is ejected, but the incident X-ray photons come out with lower energies. O The incident X-ray photons are completely absorbed to the electrons in a higher orbital, and these electrons come out of the atoms as free electrons. No photon comes out during this process. O The incident X-ray photons are partially absorbed to the electrons in a higher orbital, and these electrons come out of the atoms as free electrons. The incident X-ray photons come out with lower energies. D Question 6 1 pts The energy of a photon is given by 8.2 x 10-16 J.
