1.	What is ligh? write it\'s properties
Answer» Light is a form of energy that produces in us the sensation of sight.Following are the properties of light:\tReflection of light: Every light follows the law of reflection which states that the angle of incidence is equal to the angle of reflection.\tRefraction of light: Refraction of light takes places when the light ray changes its velocity it passes from one medium to another. Index of refraction is used as a means to measure how much light refracts.\tDispersion: Dispersion of light is defined as the process in which the white light separates into different colours based on their wavelength when passed through a glass prism.
