Thanks :) My way was a different one how do i know my way is wrong :(
you assumed that the particle was still moving while it had stopped moving at maximum point so the velocity was zero. it means all of the kinetic energy is changed into other forms of energy.
we can easily see that the potential energy has increased.
but the potential energy has not changed by same amount.
the rest went to the internal energy/doing work against air resistance.

As it Goes away Reading Decreases And reaches Minima Then start to Increase Uptil NExt Maxima.! Last Maxima will be At P! Then there will be many Maxima/Minima In between P and O!
now u can See from Figure the Path difference is 0.15 (0.9-0.75). And wave lenght we calculated Is 0.025..
So 0.15/0.025= 6 Wavelengths.. Meaning 6 Maxima And Minima! We add one Maxima At O (where Path diffrence is O) to make it 7 Maxima And 6 Minima..!
Samjh Aya .. Or u need detailed Explaination :p!

i assumed the this was suppose to the k.e but this was lost because of the air Resistance

o_O why are you apologizing i was trying to understand if my method is wrong and as you explain the best thank you on how to find it the marking scheme way
I apologized for initially stating that your approach was wrong and yielded correct result as a mere chance but your approach was just as sensible as the one in the marking scheme.
