Question

69. What is the wavelength of a ball when it is moving with 6.625x10-14 Kg.m/s
momentum
​

Answer 1

Answer:

According to de Broglie's equation

λ= mv

h

where, λ= de-Broglie wavelength

h=6.626×10 −34

Js=Planck's constant

m=mass of object=200 g= 0.2 kg and v= velocity=5m/h=5/3600 m/s

upon substitution we get:

λ= 0.2×56.626×10 −34 ×3600

λ=2.385×10 −30m
