Question

Problem 5 Find the de Broglie wavelength for the following objects: a) 66.2 kg person moving at 10 meters per second. b) 1.3 x10-27 kg molecule moving at 1 centimeter per hour.

Answer 1

@ Given that .: Mass of person (m) = 66,2 kg Speed (V) = 10 m/s de broglie wave leng this given by we know that I h 1= miel where da de broglie.wavelength ma Mass ☺ = speed . h = 6.626 * 1034 J. sec 6.626 10-34 66.2 * 10 -36 He b0009 * 10m - 36 n=1.000 9 * 10 36 m a 1*10 30 metery
