actually i have my exam and i am really weak in quantum mechanics ... i would like to know another question sir ... i know the physical meaning of normalization , will you please tell me the physical meaning of orthogonality ? i have one more small assignment too .. i tried but unable to do...

sir , 1 more thing .. will you please explain me that why do we need operators in quantum mechanics ? i mean i can understand that momentum and position can't be measured simultaneously... we can't get exact momentum value if position is defined and vice versa . But how does operator helps in...

i.e its 2nd derivative is infinite which means its energy is infinite but i think that is not practically possible ... so does it mean that schorodinger equation can't be applied for this type of potentials ...

I read somewhere that as mod of the square of a wave function gives the probability of finding a particle hence it must be square integrable, must be finite everywhere i.e must be a bound state so that the probability is finite .As wave function satisfy Schrodinger equation , so it must be...
