standard notation b What is the frequency of the wave in Hertz Report your answer in scientific notation nm 10 Hz c If the wavelength of the wave is halved what will happen to the speed of light c A c will be doubled B c will increase but not double C c will be halved D c will decrease but not in half E c will not change d If the wavelength of the wave is halved what will happen to the frequency A will be doubled B will increase but not double C will be halved D will decrease but not in half E will not change 2 Consider the two waves illustrated below line hashmarks included for scale Which of the following statements is false A Wave A has a shorter wavelength than Wave B B Wave B has a lower amplitude than Wave A C Wave B has a lower energy than Wave A D If Wave A corresponds to blue light then wave B could correspond to infrared radiation E None of the above are false 3 Which of the following photons has the shortest wavelength A Visible green B Microwave C Visible red D Infrared E Radio 4 What is the wavelength m of a photon with a frequency of 195 MHz Report your answer in standard notation m 5 Laser tattoo removal is commonly employed using lasers of various wavelengths If the wavelength of a particular laser is 532 nm what is its energy in Joules What is its frequency in Hertz Report your answers in scientific notation 10 10 J Hz 6 Light is shined onto a metal such that the frequency of the light is below the threshold frequency If the frequency of the light is increased above the threshold frequency which of the following statements are true Select any that apply and answer using capital letters with no spaces e g ABCDE A The energy of the light increased B The wavelength of the light increased C Photons are ejected from the metal after the light is changed D Electrons are ejected from the metal after the light is changed E Electrons are absorbed by the metal after the light is changed 7 Watson and Crick were awarded the Nobel Prize in 1962 for the discovery of DNA but it was Rosalind Franklin s research group who collected Photo 51 an x ray diffraction image that was critical in this discovery The diffraction image clearly illustrated diffraction spots throughout the pattern shown below by the red arrows which was a result of x rays diffracting off of the DNA structure Based on this information which of the following statements is are true Select any that apply and answer using capital letters with no spaces e g ABCDE Hint the diffraction spots were a result of increased amplification A The spots seen were a result of destructive interference B The spots seen were a result of constructive interference C The x rays used in this experiment had a higher wavelength than infrared or microwave radiation D The x rays used in this experiment had a lower wavelength than infrared or microwave radiation E The x rays used in this experiment had higher energy than infrared or microwave radiation F The x rays used in this experiment had lower energy than infrared or microwave radiation 8 Consider an electron that transitions from the n 4 level to a lower energy level a In which transition would the resulting photon produced be at the shortest wavelength Answer by using an integer e g 0 1 etc n b Which transition most likely correlates to the emission of light recorded in the illustration below Answer by using an integer e g 0 1 etc n 4 n n 4 n n 9 Which of the following options below will have the smallest de Broglie wavelength when moving at the same velocity A a chemistry book B a titanium atom C a sheet of paper D a drop of water E The planet earth F There is not enough information to determine this 10 A student walks into their General Chemistry I exam and they realize they have forgotten their nonprogrammable calculator A prepared friend carefully throws a calculator to them at a velocity of 0 520 m s If the calculator has a mass of 113 grams what is the calculator s wavelength in m A 1 13 10 35 m B 1 50 m C 1 50 10 12 m D 1 13 10 32 m E 0 780 m F 0 780 10 12 m 11 Which statements are true based on the Bohr model of the atom Select any that apply and answer using capital letters with no spaces e g ABCDE A Atomic emission spectra are due to electrons …
