1. Path of light is unaffected by presence of external magnetic field.

  2. Wave front is the locus of all the vibrating particle in the same phase. for example, an almond is dropped in a bucket full of milk, you can notice the circular wavefront generating on the surface of milk.

    Wavelet is simply an oscillation that increases from zero reach to maximum and maximum to zero.

  3. The differences are:


    A wavefront is the locus of all the particles which are in phase.

    A wavelet is a point on any given wave front which acts as a new source of disturbance to move in all possible directions with the velocity of light.
