Question

the the wavelength associated with a golf ball weighing 200g and moving at a speed of 5m/h is of the order :

Answer 1

The wavelength associated with a golf ball weighing 200g and moving at a speed of 5m/h is of the order $2.36\times 10^{-30}m$

Explanation:

To calculate the wavelength of the ball, we will use the equation given by De-Broglie, which is:

$\lambda=\frac{h}{mv}$

where, $\lambda$ = Wavelength of the ball = ?

h = Planck's constant = $6.6\times 10^{-34}kgm^2/s$

m = Mass of the ball = 200 g = 0.2 kg

v = velocity of ball = 5 m/hr =  0.0014 m/s  ( 1 m/hr = 0.00028 m/s)

Putting values in above equation, we get:

$\lambda=\frac{6.6\times 10^{-34}kgm^2/s}{0.2kg\times 0.0014m/s}$

$\lambda=2.36\times 10^{-30}m$

The wavelength associated with a golf ball weighing 200g and moving at a speed of 5m/h is of the order $2.36\times 10^{-30}m$
