A kaleidoscope is an optical instrument with two or more reflecting surfaces inclined to each other in an angle, so that one or more (parts of) objects on one end of the mirrors are seen as a regular symmetrical pattern when viewed from the other end, due to repeated reflection.

The reflectors (or mirrors) are usually enclosed in a tube, often containing on one end a cell with loose, colored pieces of glass or other transparent (and/or opaque) materials to be reflected into the viewed pattern.

Rotation of the cell causes motion of the materials, resulting in an ever changing viewed pattern.

Electronic dance music (also known as EDM, dance music, club music, or simply dance) is a broad range of percussive electronic music genres made largely for nightclubs, raves, and festivals.

EDM is generally produced for playback by disc jockeys (DJs) who create seamless selections of tracks, called a mix, by segueing from one recording to another.

EDM producers also perform their music live in a concert or festival setting in what is sometimes called a live PA.

In the United Kingdom and in continental Europe, EDM is more commonly called 'dance music' or simply 'dance'.

Luminescence is emission of light by a substance not resulting from heat; it is thus a form of cold-body radiation.

It can be caused by chemical reactions, electrical energy, subatomic motions, or stress on a crystal, which all are ultimately caused by Spontaneous emission.

This distinguishes luminescence from incandescence, which is light emitted by a substance as a result of heating.

Historically, radioactivity was thought of as a form of "radio-luminescence", although it is today considered to be separate since it involves more than electromagnetic radiation.

The term 'luminescence' was introduced in 1888 by Eilhard Wiedemann.

A rave (from the verb) is a large dance party featuring performances by DJs and occasionally live performers playing electronic music.

The music is amplified with a large, powerful sound reinforcement system, typically with large subwoofers to produce a deep bass sound.

The music is accompanied by laser light shows, projected images, visual effects and fog machines.

The word "rave" was first used in the late 1980s to describe the subculture that grew out of the acid house movement.

Diffraction refers to various phenomena that occur when a wave encounters an obstacle or a slit. It is defined as the bending of light around the corners of an obstacle or aperture into the region of geometrical shadow of the obstacle.

In classical physics, the diffraction phenomenon is described as the interference of waves according to the Huygens–Fresnel principle.

These characteristic behaviors are exhibited when a wave encounters an obstacle or a slit that is comparable in size to its wavelength.

Similar effects occur when a light wave travels through a medium with a varying refractive index, or when a sound wave travels through a medium with varying acoustic impedance.

Diffraction occurs with all waves, including sound waves, water waves, and electromagnetic waves such as visible light, X-rays and radio waves.
