Wave Properties of Light Post assessment#31

Postby Peter Dis1G » Wed Oct 18, 2017 4:05 pm

Calculate the de Broglie wavelength of a 0.155 kg ball travelling at 85.0 m.s-1. Can we detect this wavelength or observe the wavelike characteristics of this ball? I am stuck on second one. Can anyone tell me when we can or can't detect wavelength? Thanks.

Typically, if the wavelength is smaller than 10^-15 m, it cannot be detected or experimentally verified in the lab.

To add on to the first response, we are generally unable to observe wave-like behaviors in large objects like baseballs. Because electrons are so small, we can measure wavelength and frequency, but not enough wave-like properties are visible in a larger object to actually make a difference. They are just much too large.
