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!

practical process described pest part of scientific investigation.

because practical knowledge is powerful then therotical knowledge.
