You irradiate a crystalline sample that has 2.9344 å between atoms with electrons to do an electron diffraction experiment in reflection mode. you observe a first order (m = 1) diffraction peak at θ = 12.062°. what is the wavelength of the electrons?

Å

Explanation:

Bragg's Law refers to the simple equation:

In this case:

n=1

θ = 12.062°

d=2.9344 Å

Å

it should be -8.6 cm hope this out

  distance on the y-axis and time on the x-axis.

explanation:

the instantaneous velocity = change in position/time taken

the slope of the graph should give instantaneous velocity.

  slope of a graph = change in value of y -axis / change in values of x -axis

  comparing both the equations

    change in value of y -axis = change in position

  change in values of x -axis = time taken

so position values should be on the y axis and time values should be on the x axis.

distance on the y-axis and time on the x-axis.
