Question

What would happen if we expand the box instead of compressing it?
A. Electron speeds decrease.
B. Electron speeds remain constant.
C. Electron speeds increase.

Answer 1

Let me see if I can get the equation @563blackghost

Answer 2

\[\lambda = \frac{ h }{ m_{e} v}\]

Answer 3

Do those variables look familiar to you?

Answer 4

It basically means, the wavelength is equal to Plank's constant divided by product of the mass of the electron multiplied by it's velocity.

Answer 5

*notes down* mkay

Answer 6

Wavelength is measured in meters, and velocity in m/s

What we get is an inverse relationship between distance and speed.

Answer 7

or 'velocity'

Answer 8

So if the box is expanded, what do you think will happen to the velocity of the electrons?

Answer 9

it would slow down?

Answer 10

Correct
