Æ Requires an understanding of atomic structure Roy A. Lacey, Stony Brook University; Che 131, Fall 2017 3 Atomic Structure Electrons are situated at comparatively large distances (compared to nuclear dimensions) around the nucleus The interaction of radiation with atoms plays an important role in the study of atomic structure Roy A. Lacey, Stony Brook University; Che 131, Fall 2017 4 Electromagnetic spectrum The electromagnetic spectrum is a continuous range of radiant energy. Waves are crucial for characterizing Electromagnetic radiation High frequency/short wavelength Low frequency/long wavelength

Lacey, Stony Brook University; Che 131, Fall 2017 6 Waves ` Wavelength ( O ) is the distance from crest to crest or trough to trough on a wave. ` Amplitude of a wave is the height of the crest or depth of the trough with respect to the center line of the wave. Roy A. Lacey, Stony Brook University; Che 131, Fall 2017 7 Waves ` The frequency (f) of a wave expresses the number of times a wave passes a given point in some unit of time.

    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.
