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:

Solution Summary

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.
