Whose fringe width will be larger, the one for red light or the one for yellow light, all other things be the same?

Text Solution

Verified by Experts

we know that, fringe width,
`beta=(lambdaD)/d`
Now, for same value of D and d, `B prop lambda`
Now, `lambda_(red) gtlambda_(yellow)`
Hence, `beta_(red) gt beta_(yellow)`
Hence, fringe width will be greater when red coloured light is used.
