Study Notes
Properties of Light
- Light travels in a straight line at a speed of approximately 299,792,458 meters per second or 186,282 miles per second in a vacuum.
- It takes about eight minutes for light to travel from the Sun to the Earth.
Reflection of Light
- When light rays hit an object and bounce back as they strike a surface, it is called reflection.
- Mirrors with smooth and shiny surfaces form good images because they are good reflectors.
- Reflection occurs when light bounces back from a surface, allowing us to see our image in a mirror.
Other Properties of Light
- Light can also be refracted, transmitted, absorbed, scattered, or diffracted when it hits an object or is blocked.
- The properties of light can be observed when it interacts with an object or is blocked.
