Calculate the de Broglie wavelength of a 155-g ball traveling at 82 mph. Why is the wave nature of matter not important for this ball?

• A. 1.2×10⁻³⁴ m; The value of wavelength is so small that it will not affect the trajectory of the ball.
• B. 4.5×10⁻⁴⁴ m; The value of wavelength is so small that it will not affect the trajectory of the ball.
• C. 6.2×10⁻³⁴ m; The value of wavelength is so small that it will not affect the trajectory of the ball.
• D. 8.2×10⁻³⁴ m; The value of wavelength is so small that it will not affect the trajectory of the ball.

Answer: (A)
