Question

what will be the wavelength of a ball of mass 0.1kg moving with a velocity of 10 m/s?​

Answer 1

hey mate!

h = 6.626 × 10^-34Now ,a/c to de- Broglie equation wavelength Wavelength = h/mvNow mv = 0.1×10=1So ,wavelength =h =6.626 ×10^-34 m

Answer 2

The wavelength of a ball of mass 0.1kg moving with a velocity of 10 m/s is -$6.626\times 10^{-34}m$

Explanation:

To calculate the de-broglie wavelength:

Formula used : $\lambda=\frac{h}{m\times v}$

where,

$\lambda$ = wavelength

h = Planck's constant = $6.626\times 10^{-34}Js$

m = mass = 0.1 kg

v = velocity = 10 m/s

Now put all the given values in this formula, we get

$\lambda=\frac{6.626\times 10^{-34}Js}{0.1kg\times 10m/s}=6.626\times 10^{-34}m$
