Introduction to Light

Light is a natural agent that enables us to see and understand our surroundings. It allows us to witness the beauty of nature, such as the sunrise, sunset, and rainbow, as well as the vibrant colours of vegetation, flowers, and the deep blue sky during the day.

• At night, light enables us to marvel at the shining stars in the dark sky and observe man-made objects around us.
• Scientifically, light is electromagnetic radiation that stimulates the sense of vision. It reflects differently depending on the surface it encounters.
• Smooth and flat surfaces produce regular reflection, while rough surfaces cause irregular reflection. Light's behaviour and interaction with various surfaces play a crucial role in how we perceive the world.
