Optics is a branch of physics that deals with the determination of behaviour and the properties of light, along with its interactions with the matter and also with the instruments which are used to detect it.

Coltrane researcher Lewis Porter has written about the composition's relationship to the melody of the 1931 popular song "Shadrack" by Robert MacGimsey, which is itself believed to be based on earlier folk songs. [3] Saxophonist Sonny Rollins recorded "Shadrack" in 1951 for his Sonny Rollins Quartet 10" album, and Louis Armstrong can be seen singing "Shadrack" in the 1951 film The Strip.

Ray optics is also called geometrical optics. It is a branch of science that describes light propagation in terms of “rays”.

Hence this type of property is called wave-particle duality and the study of light in the area of physics is known as Optics.

Light is a form of energy that is in the form of an electromagnetic wave and is almost everywhere around us. The visible light has wavelengths measuring between 400–700 nanometres. The Sun is the primary source of light by which plants utilize this to produce their energy.

Optics, in a simple manner, is used to describe the behaviour of visible light, infrared light, and ultraviolet. Imaging is done with the help of a system called an image forming an optical system.

Wave optics is the branch of optics that studies the diffraction, interference, polarization, and other phenomena for which the ray approximation of geometric optics is not valid.

The bending of light when it passes from one medium to another is called Refraction. This property of refraction is used in a number of devices like microscopes, magnifying lenses, corrective lenses, and so on. In this property, when the light is transmitted through a medium, polarization of electrons takes place which in turn reduces the speed of light, thus changing the direction of light.

In physics, the term light also refers to electromagnetic radiation of different kinds of wavelengths, whether it is visible to the naked eye or not. Hence, by this, the gamma rays, microwaves,  X-rays, and radio waves are also types of light. Learn more by visiting the links below.

When a beam of light strikes the water, a part of the light is reflected, and some part of the light is refracted. This phenomenon is called as total internal reflection. Read More: Total Internal Reflection.

Reflection is one of the primary properties of light. Reflection is nothing but the images you see in the mirrors. Reflection is defined as the change in direction of light at an interface in-between two different media so that the wave-front returns into a medium from which it was originated. The typical examples for reflection of light include sound waves and water waves.

Like all the different types of light, the spectrum of visible light is absorbed and emitted in the form of tiny packets of energy called photons. These photons have both the properties of a wave as well as a particle.

The rate at which the light travels in free space is called the Speed of light. For example, light travels 30% slower in water when compared to vacuum.

It is a property of light, where the white light splits into its constituent colours. Dispersion can be observed in the form of a prism. The other properties of light include diffraction and interference. So, what do you observe when you look out at the beautiful scenario? Whether the light gets reflected, dispersed, refracted, internally reflected, or diffracted.

"Mr. P.C." is a twelve-bar jazz piece in minor blues form, composed by John Coltrane in 1959. The song is named in tribute to the bass player Paul Chambers,[1] who had accompanied Coltrane for years. It first appeared on the album Giant Steps, where it was played with a fast swing feel.[2]
