Samantha is observing a salt crystal under a microscope. she wants to view more details by enlarging the image of the crystal. which would allow her to do this?
a)increasing the amount of light that shines on the crystal
b)decreasing the amount of light that shines on the crystal
c)increasing the strength of the objective lens
d)decreasing the strength of the objective lens

Consider the particle-in-a-box problem in 1d. a particle with mass m is confined to move freely between two hard walls situated at x = 0 and x = l. the potential energy function is given as (a) describe the boundary conditions that must be satisfied by the wavefunctions ψ(x) (such as energy eigenfunctions). (b) solve the schr¨odinger’s equation and by using the boundary conditions of part (a) find all energy eigenfunctions, ψn(x), and the corresponding energies, en. (c) what are the allowed values of the quantum number n above? how did you decide on that? (d) what is the de broglie wavelength for the ground state? (e) sketch a plot of the lowest 3 levels’ wavefunctions (ψn(x) vs x). don’t forget to mark the positions of the walls on the graphs. (f) in a transition between the energy levels above, which transition produces the longest wavelength λ for the emitted photon? what is the corresponding wavele

Why don't you see your reflection in water with waves or repples

If anyone who can me with this hw? i would really appreciate it
