[Physics Class Notes] on Wave Front Pdf for Exam

A wavefront meaning is, it is the set or locus of all the points in the same phase. Here, the locus is the path travelled by a particular point emanating from the light source; however, there are millions of points like this.  All these points undergoing locus form various types of wavefronts.

There are three types of wavefront, viz: plane wavefront, spherical wavefront, and cylindrical wavefront. Moving forward, we will understand these types with the wavefront Physics and Wavefront Lasik in detail.

More About Waves

In physics, periodic waves are used to describe the propagation of radiation energy of the light, sound, wind or any other kind of energy. And because this wave is a smooth periodic oscillation, it is described as a function of sinusoidal waves. In earlier times light was described as a combination of very tiny particles that do not have any mass. It was also theorised that the particles of different coloured lights were also different. All the other natural phenomena of light such as reflection, refraction, diffraction were understood based on this hypothesis and considering that light particles are elastic in nature. 

In the 17^th century, Christian Huygens made a groundbreaking scientific revolution. He proposed that light is actually a form of energy and moves in the form of waves. He explained it by suggesting that any point source of light radiates light waves in all directions simultaneously in three dimensions. The particles in its surrounding vibrate periodically under the influence of wave energy. In this type of propagation, the points of a particular location are present at the same phase with respect to time. The plane formed by this locus of points or particles in the same phase is known as a wavefront.
