Chem exam2 study guide Study powerpoints Print periodic table no element names on table True/false The shorter the wave length the higher the energy. T Visible light makes up the largest portion of the electromagnetic spectrum F The great success of the bohr model of the atom is that it predicted the emission spectrum lines of multielectronic elements like helium. F (bohr model can solve only for 1 atom; helium=2) Electrons behave like particles and we can describe their exact paths F The higher the principle quantum number (n), the lower the orbital energy F the higher n the higher orbital energy Mult Choice Which of the statements about light is False? a. Light travels through space at a speed of 3.00 x 10^8 m/c b. light travels much faster than sound c. a packet of light energy is called a photon d. a characteristic feature of light that determines its color is its wavelength e. all of the above statements are true The number of cycles of a wave that passes a stationary point in one second is called its a. wavelength b. frequency c. crest d. trough e. none of the above Which of the following is true? a. the wavelength of light is inversely related to its engery b. as the energy increases, the frequency of radiation decreases.
