a.
Answer to Problem 26PP
de Broglie wavelength
Explanation of Solution
Given data:
Mass of the bowling ball
Velocity of the ball
Formula used:
de Broglie wavelength can be obtained by:
Here, h is the Planck’s constant, m is the mass and v is the velocity.
Calculation:
Substitute the values and solve:
Conclusion:
de Broglie wavelength of the bowling ball is
b.
To Explain: Bowling ball exhibits no observable wave behavior.
b.
Explanation of Solution
Introduction:
de Broglie wavelength can be obtained by:
Here, h is the Planck’s constant, m is the mass and v is the velocity.
Wave behavior of macroscopic objects like bowling ball is not visible because macroscopic objects have much larger mass than microscopic objects
The de Broglie wavelength is contrariwise related to the mass of the body. As the mass of the macroscopic objects is large, the de Broglie wavelength is so small that its wave nature is not observable.
Conclusion:
Hence, bowling ball’s mass is so large that its wave nature cannot be observed.
