Hi -

Pretty confident of my answer but would be grateful if an actual expert could provide their thoughts please ?

Many Thanks

The Figures below show the wave function describing two different states of a particle in an infinite square well. The number of nodes (within the well, but excluding the walls) in each wave function is related to the quantum number associated with the state it represents: number of nodes = n 1 Wave function A Wave function B Determine the wavelength of the light absorbed by the particle in being excited from the state described by the wave function labelled A to the state described by the wave function labelled B. The distance between the two walls is 4.00 x 101' m and the mass of the particle is 1.64 x 1026 kg. Enter the value of the wavelength in the empty box below. Your answer should be specified to an appropriate number of significant figures
