The band of seven colours dispersed by a glass prism is known as a spectrum.
Visible light or white light is made up of seven colours. The light waves of different colours vary in their frequency and wavelengths. When a white light is made incident on a glass prism, it undergoes refraction. The prism splits the incident white light into a band of colours. The higher frequency (lower wavelength) violet light travels slower or refracts more than the lower frequency (higher wavelength) red light. Likewise the other colour light waves bend with respect to the incident white light as they pass through the prism.
Thus, the rays of different colours emerge alone and become distinct. This band of the coloured components of a light beam is called its spectrum. The sequence of colours from bottom to top is VIBGYOR (Violet, Indigo, Blue, Green, Yellow, Orange and Red).

Crystallization is the process by which we can obtain crystals of copper sulphate. In this process, a few drops of dilute sulphuric acid is added to water. The water is then boiled & as it starts boiling, copper sulphate powder is added with stirring. The powder must be added on till the solution becomes saturated. Afterwards, it is filtered into a china dish and allowed to cool, undisturbed. After some time the crystals of copper sulphate separate out.

The way each society perceives what a 'man' is and what a 'woman' is, and what their different roles and responsibilities are, is called gender. It is more than the biological difference between men and women.

Silk is a soft thread-like fiber spun by silkworms.
Silk fibres are animal fibres obtained from cocoons of the silkworm. The rearing of silkworms for obtaining silk is called sericulture. It is a very old occupation in India.
reeling the silk:
When the cocoons are kept under the sun or boiled or exposed to steam, the silk fibres separate out. The process of taking out threads from the cocoons for use as silk is called reeling the silk. It is done in special machines, which unwind the thread or fibres of silk from the cocoon.

2(x+4) -10=44
2x + 2(4) = 44 + 10
2x + 8 = 54
2x = 54 - 8
2x = 46
x = 46/2
x = 23

Vikramashila was established by the Pala emperor Dharmapala (783 to 820) in response to a supposed decline in the quality of scholarship at Nalanda. Atiśa, the renowned pandita, is sometimes listed as a notable abbot. It was allegedly destroyed by the forces of Muhammad bin Bakhtiyar Khalji around 1193.
