🔑 Key Concepts & Definitions

Light is a form of energy which makes objects visible.

• Light is a type of energy that travels in waves and enables us to see objects when it enters our eyes. Without light, objects cannot be seen, as they do not emit or reflect any visible energy (see section 2).

Light enables us to see objects by entering our eyes.

• When light from an object enters our eyes, it is processed by our brain to form an image, allowing us to perceive the object’s shape, colour, and position.

Without light objects are not visible.

• In the absence of light, there is no energy to illuminate objects, so they remain invisible to the human eye.
