CH: 12 Atomic Theory & Quantum Mechanics 02:35 Atoms are measured in Angstroms ( Α° ) = 1 * 10^-10 m = .1 nm = 100 Pm Range from 1A ° (H) to 8A ° (Cs) All EM rad travels at C (speed of light) = 3.0 * 10^8 Sinusoidal oscillating waves of magnetic (H) and electric (E) fields Light has a dual nature of both waves and particles Frequency ( ν ) – the number of oscillations a second (measured in Hertz (Hz)) Wavelength ( λ ) – the distance (m) between correlating point of adjacent waves (measured in meters in scientific notation) C= λ * ν  (this means that wavelength and frequency are inversely proportional Radio Waves- FM (measured in MHz) and AM (measured in KHz) Ex. conversions  FM 96.7 (MHz) λ =C/ ν  = 3 EE 8 / 96.7 EE 6 = 3.1 m

    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.
