The overall lenght of path of a wave is called path lenght.  Path lenght  > = wavelength The maximum displacement of particle from its mean position where it will come to rest or from where it started with zero initial speed.

As we learned that in AP 

 a_{2}-a_{1}=a_{3}-a_{2}

\log (2^{n}-1) -\log(2)=\log(2^{n}+3)-\log(2^{n}-1)

\log(2^{n}-1/2)= \log(2^{n}+3/2^{n}-1)

(2^{n}-1/2) = (2^{n}+3/2^{n}-1)

Let 2^{n} = x

(x-1)^2 = 2x+6\Rightarrow x^2 -2x +1 = 2x +6

x^2 -4x-5=0\Rightarrow here X = 5 & X=-1 (X = -1 not possible) 

So X = 5
2^{n}= 5 (Taking log both sides we get)

n\log2 = \log5 \Rightarrow n = {log_{2}}^{5}

Hence option (B) is correct

Sir please tell the answer of this question and solving method. Two particles executes S.H.M. of same amplitude and frequency along the same straight line. They pass one another when going in opposite directions, and each time their displacement is half of their amplitude. The phase difference between them is
