The intensity at the center of a single – slit diffraction pattern is 0. What is the intensity at a point in the pattern where there is a 68.0 radian phase difference between wavelets from the two edges of the slit? (b) If this point is 9. 00° away from the central maximum, how many wavelengths is the slit wide?

What is a subatomic particle with a negative charge and very little mass?

The nuclear potential that binds protons and neutrons in the nucleus of an atom is often approximated by a square well. imagine a proton conned in an innite square well of length 105 nm, a typical nuclear diameter. calculate the wavelength and energy associated with the photon that is emitted when the proton undergoes a transition from the rst excited state (n 2) to the ground state (n 1). in what region of the electromagnetic spectrum does this wavelength belong?

12. a body is a particular amount of matter. it can be a solid, liquid or gas. it can be described as existing in a. size and shape. b. motion and force c. time and space. d. location and movement.
