You decide to roll a 0.15-kg ball across the floor so slowlythat it will have a small momentum and a large de Brogliewavelength. A.If you roll it at 1.2×10−3 m/s , what is itswavelength? B.How does this compare with the de Broglie wavelengthof the high-speed electron that strikes the back face of one of theearly models of a TV screen at 1/10 the speed of light(2.4×10−11m)?
