How do I calculate the position of the first order diffraction peak in a double-slit experiment?

The horizontal position x (measured from the optical axis) of a point on the screen at distance D from the double slit with slit separation a is related to the angle of diffraction Φ via the equation: sin Φ ...

What is the wavefunction of a particle in an infinite square well?

An infinite square well is a region with constant potential energy (inside the well) surrounded by a region of infinite potential energy (outside the well). Therefore, it is impossible for a particle to be o...
