Physical and Quantum Optics In This Chapter: ✔ Interference ✔ Diffraction ✔ Polarization ✔ Quantum Theory of Light ✔ X-rays Interference In examining the reflection and refraction of light, it is sufficient to consider light as though it consisted of rays that travel in straight lines in a uniform medium. The study of such phenomena, […]

Defects of vision and their correction
The main features of the human eye This image is a simplified diagram of the human eye. In many respects it is similar to the camera. An image is formed by the eye lens on the sensitive retina at the back of the eye, whence a message is transmitted to the brain […]

Mixing colored lights explained
This is the second part of our discussion about dispersion and color. And we’ll learn about: 1- Color of objects in white light. 2- Light filters. 3- Appearance of colored objects in colored light. 4- Primary and secondary colors. 5- Mixture of colored lights. 6- Mixing colored pigments. and 7- Infrared and ultraviolet light. […]

Dispersion and color: Newton’s experiments
It had been known for centuries that small fragments of colorless glass and precious stones glittered in bright colors when white light passed through them, but it was NOT until the middle of the seventeenth century that Sir Isaac Newton investigated the problem systematically. Newton’s work on this subject arose out of the need […]

Electromagnetic waves illustration: Origin and sources
Electromagnetic waves When the wave theory of light first gained general acceptance it was considered that light waves were conveyed through a transparent elastic medium which filled the whole of space, even a vacuum. This substance was called the ether. Michael Faraday’s move A further step forward was made in 1845, when Michael Faraday showed […]
