Answer:
here is your answer mate
hope this will help you !!!
Explanation:
The primary properties of visible light are intensity, propagation direction, frequency or wavelength spectrum, and polarization, while its speed in a vacuum, 299,792,458 meters per second, is one of the fundamental constants of natuIn a vacuum (a container with no air), light travels at the speed of approximately 299 792 458 metres per second (m/s). This is known as the speed of light. It is the fastest that anything in the universe is able to move! For comparison, the speed of sound is only approximately 300 m/s. This is why during a storm you always see lightning before hearing thunder.
An important thing to know about light is that it travels in a straight line through a material.re.
The natural agent that stimulates sight and makes things visible is called light..
Properties Of Light
Following are the properties of light:
: Reflection of light: Every light follows the law of reflection which states that the angle of incidence is equal to the angle of reflection.
: Refraction 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.
: Dispersion: 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.
