1.

Two coherent sources of wavelength 6 . 2 xx 10^(-7)m produce interference . The path difference corresponding to 10^(th)order maximum will be ?

Answer»

`6. 2 XX 10^(-6) m`
`3 . 1 xx 10^(-6) m `
`1 . 5 xx 10^(-6) m `
`12 . 4 xx 10^(-6) m `

SOLUTION :We know`Delta X = n lambda`
For `10^(TH)`order maximum
`Delta x = 10 xx 6 . 2 xx 10 ^(-7) = 6 . 2 xx 10^(-6)` m
