A rock has a mass of 100g and it is thrown across a pond at a speed of 30ms^-1. Calculate the de Broglie wavelength of the rock and explain whether you can see the wave produced.

λ=h/p λ=h/mv λ= 6.6310^-34/0.130 λ= 2.21*10^-34m We cannot see the rock's de broglie wave because its wavelength is much smaller than that of the visible spectrum
