A 2 mg sand particle is blown with a speed of `50 m//sec` what is the its de Broglie's wavelength ?
A
`3.31xx10^(-30)m`
B
`3.31xx10^(-15)m`
C
`6.62xx10^(-30)m`
D
`6.62xx10^(-15)m`
Text Solution
Verified by Experts
The correct Answer is:
C
A `2 mg` sand particle is blown with ………….. or `lambda = (6.62xx10^(-34))/(2xx10^(-3)xx10^(-3)xx50)` `= 6.62xx10^(-30)m`
