speed and wavelength problem
« on: January 26, 2006, 03:14:00 PM »
my teacher  pulled this one on me two days ago.  it has to do with speed and wave lenglth.  but i for the life of me can not figure it out.  here is the problem.

Compare by ratio the predicted wave lengths of an alpha particle moving at .85c (c = speed of light) and a 5.5 pound fish being yanked out of the water at 20 MPH.

if i could also get the work that would be great.

There is a simple equation linking mass, speed and wavelength, check your textbook.

use debroglie's equation
