In the beginning wave theory of light was not accepted due to Corpuscular theory proposed by Sir Isaac Newton.
Corpuscular theory states that the speed of light increases from rarer to denser medium. Frequency is the number of peaks that travels beyond a point in one second.
A collection of rays incoming from the left are refracted twice by the lens, once on entry and once on exit, and the net result is the accumulation of all rays at a focal point on the right.
After this, many other experiments were carried out which included the interference, diffraction and polarization patterns. Later scientists found out that light travels both in the form of waves and particles.
Glauberand Leonard Mandel applied quantum theory to the electromagnetic field in the s and s to gain a more detailed understanding of photodetection and the statistics of light. Sometimes light travels in the form of waves too. Physical optics predicts that the shape of the focal spot will remain unchanged; it will just grow less bright.
My physics specialization and area of research is optical science.
Some light moves in long waves whereas,some other moves in the form of short waves. Physical optics lies on the boundary of engineering and pure science, as new physical consequences of the wave nature of light are still being uncovered and optical devices are being built which take advantage of this wave nature.
The law of reflection says that the reflected ray lies in the plane of incidence, and the angle of reflection equals the angle of incidence. From the laws of reflection and refraction, one can determine the behavior of optical devices such as telescopes and microscopes.
Bacon was able to use parts of glass spheres as magnifying glasses to demonstrate that light reflects from objects rather than being released from them. But this concept was not readily accepted and was in contradiction to the particle theory or the corpuscular theory of light proposed by Sir Isaac Newton.
Finally wave theory came into existence. For our purposes, the wavelength may be considered a distance over which wave effects are typically apparent.
He was also able to correctly deduce the role of the retina as the actual organ that recorded images, finally being able to scientifically quantify the effects of different types of lenses that spectacle makers had been observing over the previous years.
The first wearable eyeglasses were invented in Italy around Optics, the branch which is the study of light phenomena is divided into two-ray optics and wave optics. Wave Optics deals with the study of various phenomenal behaviors of light like reflection, refraction, interference, diffraction, polarization etc.
Huygens mentioned that light travels in the form of waves.
Specialty areas of optics research include the study of how light interacts with specific materials as in crystal optics and metamaterials. Other research focuses on the phenomenology of electromagnetic waves as in singular optics, non-imaging optics, non-linear optics, statistical optics, and radiometry.
In a wave we have to distinguish between the speed of transport of energy or the speed of the transport of on phase state of a wave of a defined frequency. In vacuum the speed of waves of any photon energy - wavelength is the same, but the transmission speed through material is dependent on wavelength -.
