A sub-atomic particle of mass 1 0 − 30 kg is moving with a velocity 2.21 × 1 0 6 m / s . Under the matter wave consideration, the particle will behave closely like ( h = 6.63 × 1 0 − 34 J . s )

λ = p h = 1 0 − 30 × 2.21 × 1 0 6 6.63 × 1 0 − 34 = 3 × 1 0 − 10 m Hence particle will behave as x-ray.

A sub-atomic particle of mass $1 0^{- 30} kg$ is moving with a velocity $2.21 \times 1 0^{6} m / s$ . Under the matter wave consideration, the particle will behave closely like $(h = 6.63 \times 1 0^{- 34} J . s)$

Options:

Answer:

Solution:

$λ = \frac{h}{p} = \frac{6.63 \times 1 0 ^{- 34}}{1 0 ^{- 30} \times 2.21 \times 1 0 ^{6}} = 3 \times 1 0^{- 10} m$

Hence particle will behave as x-ray.
