A) 2 cm, 7.5 cm
B) 3 cm, 6 cm
C) 2 cm, 4 cm
D) 4/3 cm, 10/3 cm
Correct Answer: C
Solution :
Fringe width b µ l. Therefore, l and hence b decreases 1.5 times when immersed in liquid. The distance between central maxima and 10th maxima is 3 cm in vacuum. When immersed in liquid it will reduce to 2 cm. Position of central maxima will not change while 10th maxima will be obtained at y = 4cm.You need to login to perform this action.
