What are the properties of light?

 Light shows several important properties:

1. Light travels in a straight line: This property is known as rectilinear propagation of light. It explains why shadows are formed and why we cannot see around corners.
2. Formation of shadows: When light is blocked by an opaque object, a shadow is formed behind it. The shape of the shadow depends on the object.
3. Reflection of light: Light can bounce back from surfaces like mirrors, allowing us to see images.
4. Light does not require a medium: It can travel through a vacuum, such as space.
