Answer to Question #290586 in Quantum Mechanics for Sri

Question

1)Suppose the temperature of a COVID positive patient is recorded as Tbody = 40°C. Determine the wavelength at which the radiation emitted from the body reaches its peak.

2) Derive the energy and wave function of a particle present in the n th state bounded in a length of ‘L’ subjected to boundary conditions 0 < x < L ?

3) An electron is bound in one dimensional potential well of width 0.2 nm. Find the energy value in eV of the third excited state.

4) Why uncertainty principle is not applicable to human? Electrons moving with a velocity of 4.5 × 105 m/s if this velocity is measured with an inaccuracy of 0.5 % then estimate the uncertainty in the position of an electron?
