Light
The discussion on what is light and how light can travel through space still hasn't got a complete explanation from scientists as they are quite baffled by this. This sun is a natural source of light. Shadows form when light is blocked from the sun. Light coveres approximately 300,000km every second.
Light travels as a wave and is a form of radiation. Other forms of radation include UV rays from the sun, gamma rays, x-rays and microwaves. Light is transferred through space at a speed of 300,00 kilometers per second.
Light- Law of Reflection
This law states that the angle of incidence ray is equal to the angle of the reflected ray (bouncing off the mirror around an imaginary line) the normal which is drawn at right angles to the mirror.
Refraction
-Light is bent as it travels through different mediums
Just say for example light was travelling through a medium such as a prism at first the speed would travel quickly through the air, once it hits the object the speed of light slows down through the solid prism and has a slight bend as it makes it's way through the object. Once it has left the object it slightly bends again and increases its speed as it had left the solid.
