bro tyo wave length jhukauna deko haina
yo question lai arko method bata garda wavelength ne chainxa
fringe width at air(B)= λ * D /d....(1)
fringe width at water(B')= λ' * D /d...(2)
dividing eqn i by ii garda hamlai λ' ko value chainxa jun hamle λ'=λ/mui bata nikalcam
any ways😌 thank for your help ful video just maile vanna matra khijeko hai wavelength ko ne use xa tya vanera.😊 no offence 💝
