Question

What prevents detection of the ball's wave nature?

Options

• Its de Broglie wavelength is extremely small.

• Its de Broglie wavelength is comparable to X-ray wavelengths.

• Matter waves are not associated with moving balls.

• Its mass and speed give no momentum.

Answer 1

The ball has an associated matter wave, but its wavelength is only \[1.47\times10^{-34}\ \mathrm{m}\]. Such an extremely small wavelength makes its wave nature impossible to detect.
