Photoelectric effect: when light falls on a metal surface, electrons are emitted with kinetic energy K.
Some experimental facts:
The maximum value of K is independent of the light intensity.
No electrons are emitted if the incident photon frequency is below a threshold value.
K increases with increasing photon frequency.
Light is a stream of quanta (photons). Each photon has energy E = hf, where h is Plancks constant and f is the frequency.
A photon gives all its energy to a single electron.
K_max = hf W, where W is the work function.
Compton scattering: when a photon is scattered from an electron, a change in wavelength of the photon takes place.

Lecture Slides are screen-captured images of important points in the lecture. Students can download and print out these lecture slide images to do practice problems as well as take notes while watching the lecture.
The book offers a complete review of your AP course, strategies to give you the edge on test day, and plenty of practice with AP-style test questions. It includes full length practice exams modeled on the real test and all the terms and concepts you need to know.
This book includes a review of all the topics tested including vectors, kinematics, fluid mechanics, optics and nuclear physics. Additionally, the book includes two full length tests made complete with descriptive solutions, and quick study tables for Physics B formulas and equations.
