An particle is confined in a one-dimensional "infinite potential well" of width 2a. < -a v (x) 0 -axa (a) derive an expression for the energy eigenvalues ek of this system. (b) if the above particle is an electron, and the width of the box is 2a 5.29 x 10-11m, what is wavelength of the photon emitted if the electron transitions from its first excited state to its ground state? problem-2 at what locations a inside the box would vou expect to never observe an electron in its first excited state?

Fgiryhfdashnmhddvn,

Then the answer would be d then

During the 1800s. hope this !

You need to be more specific.  i really don't know what a "motion map" is.you can draw a graph of an object's position, distance, displacement, speed,velocity, or acceleration versus time, or you can draw a graph of the object's x-position versus its y-position and not give any information about time at all.if the graph presents position or displacement against time,  then constant velocity is a straight line . . i.e. a line that has  constant slope.if the graph shows speed against time, then constant velocityis a horizontal piece of line.if the graph shows acceleration against time, then constant  velocity is a piece of line that lies on the x-axis . . it's value is zero.
