Q___ A ball weight 25g moves with a Velocity of 6.6 × 10^4 cm/s then find out the de-broglie associated with it____?

No Spams​

Answer 1

$\huge\underline\purple{\sf Answer:-}$

★$\large{\boxed{\sf \lambda =4×{10}^{-33}kg}}$

$\huge\underline\purple{\sf Solution:-}$

★Given :-

Mass (m) = 25 g

Velocity (v) = $\sf{6.6×{10}^{4}m/s}$

$\large{\sf \lambda =?}$

FORMULA TO CALCULATE WAVELENGTH IS :-

★$\large{\boxed{\sf \lambda={\frac{h}{m×v}}}}$

Here,

$\large{\lambda}$= Wavelength

m = mass

h = Planck Constant

its value is $\sf{6.6×{10}^{-34}J}$

ON PUTTING VALUE :-

$\large{\sf \lambda={\frac{6.6×{10}^{-34}×{10}^{7}erg}{25×6.6×{10}^{4}cm/s}}}$

$\large\implies{\sf 0.04×{10}^{-31}cm}$

★$\large\red{\boxed{\sf \lambda=4×{10}^{-33}cm}}$
