The amplitude is _________________________________________________________________. The frequency, ν, is the _______________________________that pass a point in a _________________________. frequency units are hertz, (Hz) or cycles/s = s‐1 1 Hz = 1 s‐1 The wavelength and frequency of a wave are related by the following equation: ν (s ‐1 c () m s ) = λ (m) Where c is the speed of light in a vacuum = 3.00 x 108 m/s Einstein proposed that the light energy was delivered to the atoms in packets, called ___________________ The energy of one _________________ can be found using the equation: E = hν = h•c λ Where h is Planck’s Constant = 6.626 x 10‐34 J∙s The energy of a photon of light is directly proportional to ______________________ and inversely proportional to __________________________________.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
