Question

a cricket ball of 0.5 Kg is moving with a velocity of 100 m/s.the wavelenght associated with its motion is

Answer 1

$\huge\underline\purple{\sf ♢Answer}$

$\large{\boxed{\sf \lambda =1.31 \times {10}^{-35}m}}$

$\huge\underline\purple{\sf ♢ Solution}$

Given :-

Mass (m) = 0.5 kg

Velocity (v) = 100 m/s

To Find :-

Wavelength $\sf{\lambda}$=?

________________________________

Formula here we use is :-

$\large{♡}$$\large{\boxed{\sf \lambda ={\frac{h}{mv}}}}$

Here ,

h = Planck Constant

it's value is $\sf{6.63 \times {10}^{-34}kg.{m}^{2}/s}$

On putting value in the formula :-

$\large\implies{\sf \lambda = {\frac{6.63 \times {10}^{-34}}{0.5 \times 100}}}$

$\large\implies{\sf 1.31 \times {10}^{-35}m}$

$\huge\red{♡}$$\large\red{\boxed{\sf \lambda =1.32 \times {10}^{-34}m}}$
