Consider, quantum mechanically, a stream of non-interacting particles of mass m each moving along the positive x direction (i. e., from left to right) with kinetic energy e=+v_0/2 toward a rectangular potential barrier given by v(x)=+ v_0 in the region -a1. with v_0=2ev, how wide must be the barrier so that the transmission probability is 10^-3.

This chart shows characteristics of three different types of waves. which statement is best supported by the information in the chart? wave x and wave y are mechanical waves, and wave z is an electromagnetic wave. wave x and wave y are electromagnetic waves, and wave z is a mechanical wave. wave x and wave z are electromagnetic waves, and wave y is a mechanical wave. wave x and wave z are mechanical waves, and wave y is an electromagnetic wave.
