    Summary of this lecture :
    1) Wave is a form of energy which is travelling by producing disturbances in its surroundings.
    2)One of the disturbances it produce is displacement, displacement is a function of x and t both.
    3)Only that functions of x and t are called waves
    a)whose double partial derivative of y wrt t is directly propotional to double partial derivative of y wrt x. [ shortcut : y = F(ax +/- bt) ]
    b)y is defined for any value of x and t.
    4) wave speed is b/a
    5) If (a) x and t has same sign than wave travels in negative x axis.
    (b) x and t has opposite sign than wave travels in positive x axis

    @1:03:00 , I solved the question somewhat Mentally Sir🤔.
    I used logic, What I did was I basically Took an arbitrary value of y=1 at both cases and Got the value of x, which implies that, the wave repeats the same amt. Of energy after that distance in given time, so I got displacement =1, and since time was given to be 2s. I got v= 0.5 m per second.
    Is the logic correct🤔
