Problem
A cricket ball of mass 150 g is bowled with a speed of 30 m s−1.
(i) Calculate the de Broglie wavelength associated with the ball. Use h=6.63×10−34J s.
(ii) Compare your result with the approximate diameter of an atom (0.1nm) and comment on whether any wave phenomena would be observable for the ball.
(iii) Give two reasons, based on your calculation and everyday experience, why matter waves associated with macroscopic bodies are not detected in ordinary situations.
