Calculate the wavelength, in meters, associated with a 1.0 x 10^2 g golf ball moving at 27 m/s (about 60. mph).

Wavelength = m

Consider a 1.0 x 10^2 g golf ball. At what speed must the ball travel to have a wavelength of 5.6 x 10^-3 nm?
Speed= m x s^-1

Question 1:

Question 2: .

Explanation:

The de broglie wavelength is given by

where is the mass of the ball, is its velocity, and is the plank's constant.

Now, in the case of the golf ball

;

therefore, the de broglie wavelength is

For the second question

,

therefore the de broglie relation gives

solving for we get:

which is way larger than the speed of light, and therefore, the golf ball can never have this wavelength!
