Question

a cricket ball having mass 20mg moving with velocity 20ms calculate debroglies wave length of a cricket ball​

Answer 1

Answer:

The de-broglie wavelength of a moving object is of mass m with speed v is given as

λ=

mv

h

=

0.12kg×20m/s

6.62×10

−34

J.s

=2.7583×10

−34

m

please give me votes

Answer 2

Answer:

Here is your answer

Explanation:

mass = 20 mg = 0.00002 kg

velocity = 20 m/s

wavelength =??

$lambda = [ h/mv ]$

            = 6.626*10-34/0.00002*20

            = 1.6525*10^-30 m
