A beam of helium atoms moves with a velocity of `2 xx 10^(4) ms^(-1)`. Find the wavelength of paritcles constituting with the beam .
Hint `:` Mass of helium atom `= ( 4)/( 6.022 xx 10^(23)) g`

Explanation

To find the wavelength of the particles constituting a beam of helium atoms moving with a velocity of \(2 \times 10^4 \, \text{m/s}\), we can use de Broglie's equation:

\[ \lambda = \frac{h}{mv} \]

where:
- \(\lambda\) is the wavelength,
...
