Today, we went over "Young's Experiment Problems" worksheet.
We used the equation:
Wavelength = xd/L
We also talked about The Photoelectric Effect and the Wave-Particle Duality. According to the book, photoelectric effect is the emitting of electrons when electromagnetic radiation falls on an object. It can be studied through a photocell. Electrons are ejected only if the frequency if the radiation is above a certain minimum of value called the threshold frequency (fo). Albert Einstein studied and explained the photoelectric effect and he describes it as discrete bundles of energy called photons.
