What is light a form of?
What is light a form of?
Electromagnetic energy is a form of energy that travels in waves and includes visible light, radio waves, X-rays, and more.
What does the Law of Reflection state?
What does the Law of Reflection state?
The Law of Reflection states that the angle of incidence, which is the angle at which light strikes a surface, is equal to the angle of reflection, which is the angle at which light bounces off the surface. This applies to flat surfaces only.
How can light behave?
How can light behave?
Light can be reflected, absorbed, or refracted. Reflection is when light bounces off a surface, absorption is when light is taken in by a material, and refraction is when light bends as it passes through a medium.
