Two identical spin-zero bosons are placed in an infinite square well (Equation 2.22V(x1,x2)=−aV0δ(x1−x2)). They interact weakly with one another, via the potential (where is a constant with the dimensions of energy, and a is the width of the well). (a) First, ignoring the interaction between the particles, find the ground state and the first excited state—both the wave functions and the associated energies. (b) Use first-order perturbation theory to estimate the effect of the particle– particle intera

The intensity of a polarized electromagnetic wave is 12 w/m^2. part a) what will be the intensity after passing through a polarizing filter whose axis makes the angle θ=0∘ with the plane of polarization? part b) what will be the intensity after passing through a polarizing filter whose axis makes the angle θ=30∘ with the plane of polarization? part c) what will be the intensity after passing through a polarizing filter whose axis makes the angle θ=45∘ with the plane of polarization? part d) what will be the intensity after passing through a polarizing filter whose axis makes the angle θ=60∘ with the plane of polarization? part e) what will be the intensity after passing through a polarizing filter whose axis makes the angle θ=90∘ with the plane of polarization?
