The question is already asked earlier in the thread. The ans is A as the circuit is unchanged.Octahedral said:Can someone please explain this?The answer to this is A
RafaySid said:The answer is A, but can anybody explain me properly why are we subtracting the velocities? Don't we add the velocities when they are in the opp directions and subtract when they're in the same direction?? :%)

Please explain Question 26.
Total maxima = 2 x highest maxima + 1
highest maxima = line spacing/wavelength
line spacing = 1/(300 x 10^-3)
highest maxima = (1/300x10^-3) /( 450 x 10^-9)
= 7.4 x 10^6
2(7.4 x 10^6) + 1 = 14.8 x 10^7
= 15 when you round it off
So answer is D
For almost 10 years, the site XtremePapers has been trying very hard to serve its users.
However, we are now struggling to cover its operational costs due to unforeseen circumstances. If we helped you in any way, kindly contribute and be the part of this effort. No act of kindness, no matter how small, is ever wasted.
