- 23 An electron in a one-dimensional infinite potential well of length L has ground-state energy E₁. The length is changed to L' so that the new ground-state energy is E₁ = 0.800E₁. What is the ratio L/L?arrow_forward1C.3arrow_forwardChemistry Τhe operators l+ = lx + ily and l- = lx -ily The operators play an important role in the quantum mechanical view of angular momentum. Calculate the product l+l- function of only l^2 and lz using the relations l^2= lx^2 +ly^2 + lz^2, [lx, ly] = ihlz, [ly, lz] = ihlx and [lz, lx] = ihly.arrow_forward

In that universe, which of the following objects would require quantum mechanics to describe, that is, would show both particle and wave properties? Which objects would act like everyday objects, and be adequately described by classical mechanics? object quantum or classical?
