1 In a biprism experiment the micrometer readings for zero order and tenth order fringes are 1 25 mm and 2 37mm respectively when light of wavelength 5 90x 105 cm is used Now 4 3 3 Marks a What will be the position of zero order and tenth order fringes if wavelength is changed to 7 50x 10 cm b If a mica sheet of thickness 0 020 mm and 1 59 is introduced to cover one half of the biprism deduce the position of the zero order fringe
