Double bonds in hydrocarbons are indicated by replacing the suffix -ane with -ene. If there is more than one double bond, the suffix is expanded to include a prefix that indicates the number of double bonds present (-adiene, -atriene, etc.). Triple bonds are named in a similar way using the ... Read More

A colloid is a substance microscopically dispersed evenly throughout another substance.It can be insoluble or soluble particles which are suspended throughout another substance. The dispersed-phase particles have a diameter between about 5 and 200 nanometers. Examples: Milk is a colloidal solution.

Light is a transverse and electromagnetic wave that can be seen by the typical human eye. The wave nature of light was first illustrated through experiments on diffraction and interference. Like all electromagnetic waves, light can travel through a vacuum. The transverse nature of light can be demonstrated through polarization.Read More
