PLEASE HELP I’VE BEEN STUCK FOR HOURS!! A person stands 6.00 m from a speaker, and 8.00 m from an identical
speaker. What is the wavelength of
the first (n = 1) interference minimum
(destructive)?
(Speed of sound = 343 m/s)
(Unit = m)

An electron is trapped at a defect in a crystal. the defect may be modeled as a one-dimensional, rigid-walled box of width 1.00 nm. (a) sketch the wavefunctions and probability densities for the n 1 and n 2 states. (b) for the n 1 state, nd the probability of nding the electron between x1 0.15 nm and x2 0.35 nm, where x 0 is the left side of the box. (c) repeat (b) for the n 2 state. (d) calculate the energies in electron volts of the n 1 and n 2 states

Compare the patterns of the two waves shown in the image. which statement is true about these waves?

What energy transformations occur each time the skateboarder rolls up the ramp?
