Question

According to de Broglie, matter should exhibit dual behaviour, that is both particle and wave like

properties. However, a cricket ball of mass 100 g does not move like a wave when it is

thrown by a bowler at a speed of 100 km/h.

(a) Calculate the wavelength of the ball. 3

(b) Explain why it does not show wave nature.​

Answer 1

this is the answer to (a)

b) According to de Broglie, every object posseses a dual nature, but we cannot observe that in ordinary objects because of their large masses,e.g. the ball, since wavelength is inversely proportional to mass.
