Oscillator. consider a h1271 molecule (force constant 313.8 n m1, equilibrium bond length 161 pm) in its vibrational ground state. (a) plot the probability density function (in pm1) as a function of the bond length (in pm). (b) calculate the probability of finding the molecule with its bond length 157 pm or shorter. [you will need the error function, look it up. use a computer to evaluate it (e. g. wolfram alpha website)]

the order for strong to weak forces such as

strong nuclear force → electromegnetic force → weak nuclear force → gravitational force

the fundamental forces are those forces that act between to objects or element to make interactions. there are four types of fundamental forces such as strong and weak nuclear forces (due to protons and electrons), electromagnetic force (due to the motion of electrons) and gravitational force (due to orbital movement of the planet). if these forces are arranged on the basis of their maximum strength then the order is

strong nuclear force → electromegnetic force → weak nuclear force → gravitational force

54 degrees incident angle = reflected angle

angle is from normal turned to line of ray
