Nagoor vali, Wave expression is derived from the tangent drawn at a point and then and it is like function of cos.

hi,, nagoorvali..
in the wave optics y=acos(kx-wt) is called wave equation this is my answer … all the best for your global furtue.

this is the wave equation. the tangent drawn to the line at any point is called wave equation......... all the best ….….….…...

dear nagoorvalli ,
the wave equation is derived from the maxwells equations.it is derived from the tangent drawn at a point and it is like cos function.

my dear nagoorvali the wave expression is derived from A cos(wt) the wave is propagating periodically that`s why we taken cos function

Hello Nagoor
The wave equation which applies to a stretched string or a plane electromagnetic wave. The mathematical description of a wave makes use of partial derivatives.

Dear Nagoor Vali
The tangent drawn to any point is called wave equation.THat will be derive form other forms wave
