Question

Solve this:
22 A monochromatic light passes through a glass
slab ( μ = 1 5) of thickness 9 cm in time t1 If it
takes
a time t2 to travel the same distance through water
( μ = -4/3) The value of (t1-t2) is
l) 5 x 10-11 sec 2) 5 x 10-8 sec
3) 2 5 x 10-10 sec 4) 5 x 10-10 sec

Dear
Student,
Please find
below the solution to the asked query:
Case I:t1=dv1   =dcμ1   =dμ1c   =0
9×323×108   =4
5×10-9 sCase II:t2=dv2   =dcμ2   =dμ2c   =0
9×433×108   =4
0×10-9 sDifference of t1 and t2 :△t=4
5×10-9-4 0×10-9      =0
5×10-9 s      =5×10-10 s
