Interference between two sources will be observed if the sources are
Coherent (maintain a constant phase difference)
Monochromatic (both sources have the same single wavelength)
To have coherent sources, use a single source with 2 slits.
In Youngs double slit experiment, bright and dark fringes are obtained on a screen. The bright fringes result from constructive interference, whereas dark fringes result from destructive
Youngs experiment established conclusively the wave nature of light: waves interfere, particles dont.

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.
