The definitions for both these terms are different, so it seems to me that they are not same. But I wasn't able to find an example which illustrates the difference between these two.

Linear polarization diagram

Linear polarization equation

Circularly polarized wave have their magnitude of electric field vector constant, but their phase change periodically as a function of time.(i.e. the electric field vector rotate periodically as a function of time)

Linearly polarized wave is same as plane polarized wave. Why we call it linearly polarized ? Because oscillation taking place along a line. Why we call it plane polarized ? Since oscillation taking place along one axis & the wave is forward in motion along another axis. Two axes are used , so called plane.

Linearly polarized wave Oscillate in a single plane and the magnitude of electric field vector varies sinusoidally as a function of time.

So what exactly is the difference between a linearly polarised wave and a plane-polarised wave? Because according to me, a linearly polarised wave will oscillate in only one plane.

Since each point on the string moves on a straight line, the wave is also referred to as a linearly polarised wave. Further, the string always remains confined to the x-y plane and therefore it is also referred to as a plane polarised wave
