The wavelength difference of light waves of the wave numbers ` 2 xx 10 ^6 ` per m and 2 ` 25 xx 10 ^ 6 ` per m is

A

`0.556 xx 10^(-6)m`

B

`0.0556 xx 10^(6)m`

C

`0.0556 xx 10^(-6)m`

D

`0.556 xx 10^(6)m`

Text Solution

Verified by Experts

The correct Answer is:
C
`lambda_(1) - lambda_(2) = (1)/(lambda_(1)) - (1)/(lambda_(2)) = (1)/(2 xx 10^(6)) - (1)/(2.25 xx 10^(6))`
`= 0.0556 xx 10^(-6) m`
