  • In young' s double slit experiment, for the light of wavelength lambda_(1) fringe y_(1) and for the light of wavelength lambda_(2) fringe width is y_(2) . If the whole arrangement is dipped into a liquid of refractive index mu it is founded that for the wavelength lambda_(1) fringe width becomes y_(3) . Now the correct relation is Four light waves are represented by (i) y= a_(1) "sin" omega t " " (ii) y= a_(2) "sin" ( omega t+e) (iii) y= a_(1) "sin" 2 (omega t) " " (iv) y= a_(2) "sin" 2 (omega t +e)
