A quantity X is given by `(me^(4))/(8epsilon_(0)^(2)ch^(3))` where m is the mass of electron, e is the charge of electron, `epsilon_(0)` is the permittivity of free space, c is the velocity of light and h is the Planck's constant. The dimensional formula for X is the same as that of

A

length

B

frequency

C

velocity

D

wave number

Text Solution

Verified by Experts

The correct Answer is:
D
`X= (me^(4))/(8 epsilon_(0)^(2)ch^(3))` = Rydberg.s constant and its unit is `m^(-1)`
