The value of de broglie wavelength of an electron moving with a speed of `6.6xx10^5 m//s` is approximately equal to
`[h=6.6xx10^(-34) Js " and " m_e=9xx10^(-31) kg]`

A

21 Å

B

111 Å

C

11 Å

D

33 Å

Text Solution

Verified by Experts

The correct Answer is:
A
`lamda = (h)/(mv) = (6.6xx10^(-34))/(9xx10^(-31)xx6.6xx10^5)`
`=11xx10^(-10) m = 11 Å`
