Light is electromagnetic radiation within a certain portion of the electromagnetic spectrum . The word usually refers to visible light , which is visible to the human eye and is responsible for the sense of sight . Visible light is usually defined as having wavelengths in the range of 400  700 nanometres ( nm ), or 4 . 00 × 10 to 7 . 00 × 10 m , between the infrared ( with longer wavelengths ) and the ___MASK8___ ( with shorter wavelengths ). This wavelength means a frequency range of roughly 430  750 terahertz ( THz ). A textile or cloth is a flexible material consisting of a network of natural or artificial fibres ( yarn or thread ). Yarn is produced by spinning raw fibres of wool , flax , cotton , or other material to produce long strands . Textiles are formed by ___MASK4___ , knitting , crocheting , knotting , or felting . Silk is a natural protein fiber , some forms of which can be woven into textiles . The protein fiber of silk is composed mainly of fibroin and is produced by certain insect larvae to form cocoons . The best - known silk is obtained from the cocoons of the larvae of the mulberry silkworm " Bombyx mori " reared in captivity ( sericulture ). The shimmering appearance of silk is due to the triangular prism - like structure of the silk fibre , which allows silk cloth to refract incoming light at different angles , thus producing different colors .
