Multimedia is content that uses a combination of different content forms such as text, audio, images, animations, video and interactive content.

Multimedia contrasts with media that use only rudimentary computer displays such as text-only or traditional forms of printed or hand-produced material.

Video is an electronic medium for the recording, copying, playback, broadcasting, and display of moving visual media.

A photograph or photo is an image created by light falling on a light-sensitive surface, usually photographic film or an electronic medium such as a CCD or a CMOS chip.

Most photographs are created using a camera, which uses a lens to focus the scene's visible wavelengths of light into a reproduction of what the human eye would see.

The process and practice of creating photographs is called photography.

The word "photograph" was coined in 1839 by Sir John Herschel and is based on the Greek φῶς (phos), meaning "light", and γραφή (graphê), meaning "drawing, writing", together meaning "drawing with light".

A camera is an optical instrument for recording or capturing images, which may be stored locally, transmitted to another location, or both.

The images may be individual still photographs or sequences of images constituting videos or movies.

The camera is a remote sensing device as it senses subjects without physical contact.

The word camera comes from camera obscura, which means "dark chamber" and is the Latin name of the original device for projecting an image of external reality onto a flat surface.

The modern photographic camera evolved from the camera obscura.

The functioning of the camera is very similar to the functioning of the human eye.

In physics, sound is a vibration that propagates as a typically audible mechanical wave of pressure and displacement, through a transmission medium such as air or water.

In physiology and psychology, sound is the reception of such waves and their perception by the brain.

Humans can hear sound waves with frequencies between about 20 Hz and 20 kHz.

Sound above 20 kHz is ultrasound and below 20 Hz is infrasound.

Other animals have different hearing ranges.
