Question

de Broglie wavelength of a cricket ball with a mass of 160 gm, that is moving at a velocity of 130 km/h.

Answer 1

Step-by-step explanation:

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=

0.2×5

6.626×10

−34

×3600

λ=2.385×10

−30
