From Ancient Greece to the present day, scientists have been studying light to try to penetrate the mysteries of its composition and how to measure it...
Geometrical optics, studied in the first year, ignored the wave nature of light and so, in this course, we focus particularly on Physical Optics where the primary characteristic of waves viz. interference , is the dominant theme.
Light is a transverse, electromagnetic wave that can be seen by the typical human. The wave nature of light was first illustrated through experiments on diffraction and interference . Like all electromagnetic waves, light can travel through a vacuum.
14 Δεκ 2016 · A study of optics in the Western and Islamic cultures provides an understanding of the intellectual growth of these societies. This article attempts to retrace this history.
25 Απρ 2017 · Light Wave Experiments. Light waves, which have been found to exhibit characteristics of particles, behave in certain ways that we can observe by experimentation. Light waves diffract in the same manner that waves diffract when they collide with an object.
Envisioning light as such successive spreading of circular waves also occurs today. Light waves can be represented as shown in Figure 1.53, which presents the primary colors of the spectrum of light from the sun. Red light has the largest wavelength, violet the smallest.
