When electrons are passed through a crystal, they form a pattern on the other side that is very similar to a wave-interference pattern. what can we conclude from this result?

Explanation:

We can conclude that De Broglie's hypothesis is true. In this hypothesis the concept of matter wave was introduced, establishing that electrons have wave-like properties. Thus, all matter exhibits properties of both particles and waves, that behave in one way or another depending on the specific experiment.

the small 0.38-kg slider is known to move from position a to position b along the vertical-plane slot. determine (a) the work done on the body by its weight and (b) the work done on the body by the spring. the distance r = 0.70 m, the spring modulus k = 154 n/m, and the unstretched length of the spring is 0.53 m
