Question

what will be the wavelength of a ball of 0.1 kg moving with a velocity of 10ms-1 (use h= 6.62610-34 js)

Answer 1

Given:-

Mass of Ball = 0.1 kilogram

Velocity of the ball = 10 m/sec

Planck's Constant = 6.626 * 10^(-34) joule second

$\rule{200}{2}$

From DEBROGLIE'S WAVELENGTH EQUATION :-

We have :-

$\lambda=\bold{\dfrac{h}{mv}}$

Where,

h = Planck's Constant

m = mass of the object

V = velocity of the object

$\rule{200}{2}$

Putting the values:-

$\lambda = \dfrac{6.626 * 10^{-34}}{0.1*10}\\ \\ \\ \\ \lambda=6.626*10^{-34}$

$\rule{200}{2}$
