PASSAGE-III : Dual nature of matter was ...

PASSAGE-III : Dual nature of matter was proposed by de Broglie in 1923, it was experimentally verified by Davission and Germer by diffraction experiment.
Wave character of matter has significance only for microscopic particles. De Broglie wavelength or wavelength of matter wave can be calculated using the following relation
`lamda=(h)/(mv)`
where, 'm' and 'v' are the mass and velocity of the particle.
De Broglie hypothesis suggested that electron waves were being diffracted by the target, much as X-rays are diffracted by planes of atoms in the crystals.
The wavelength associated with a golf ball weight 200 g and moving with speed of 5 m/hr is

A

`3.72xx10^(-10)m`

B

`8.56xx10^(-20)m`

C

`2.96xx10^(-25)m`

D

`2.38xx10^(-30)m`

Text Solution

Verified by Experts

The correct Answer is:
D
`lamda=(h)/(mv)=(6.62xx10^(-34)xx3600)/(0.2xx5)m`
`2.38xx10^(-30)m`
