Calculate the "deBroglie wavelength" for each of the following:
1. an electron moving at 0.82 times the speed of light...... in meters
2. a 125-g ball moving at a speed of 13.6 m/s.....in meters
3. a 61-kg person walking at a speed of 2.00 km/hr....in meters
These answers explain why macroscopic (large) objects are not ordinarily discussed in terms of their wave-like properties because?© BrainMass Inc. brainmass.com October 16, 2018, 8:42 pm ad1c9bdddf
The solution is attached in two files which are identical in content but differ in format. One is an MS-Word document while the other is a Acrobat pdf ...
This solution shows step-by-step calculation to determine the De Broglie wavelength for the motions of the electron, ball and person. It also explains why large objects are not described in terms of their wave-like properties.
Calculate the de Broglie Wavelength for Various Objects
Calculate the de Broglie wavelength for each of the following.
a) a proton with a velocity 80% of the speed of light
b) an electron with a velocity 95% of the speed of light
c) a 190 g ball with a velocity of 10 m/s
