what makes the light moving and why it moves with this speed 299792458 mps?
What makes the waves if you throw a stone into the water? The stone. So the light switch makes the light move. Light is an electromagnetic wave that has to be "created" somewhere. E.g. by an electric current that brings the electrons of the atoms in a light bulb to a higher level and when they fall back, which they will do the same way as a pencil falls down if placed on its peak, they emit light.ahmed emad said:what makes the light moving and why it moves with this speed 299792458 mps?
Light is a form of electromagnetic radiation that is visible to the human eye. It is a type of energy that travels in waves.
Light moves in a straight line, also known as a ray. This is because it has no mass and is not affected by gravity. It can also be described as moving in a wave-like pattern.
Light is made up of particles called photons. These photons have energy and momentum, which allows them to move through space at a constant speed.
This speed, also known as the speed of light, is a fundamental constant in the universe. It is determined by the properties of the medium it is traveling through and the properties of space and time.
The speed of light is measured using various methods, including using lasers and mirrors to time how long it takes for light to travel a known distance. It can also be derived from other fundamental constants in physics, such as the permittivity and permeability of free space.
