How Does Light Travel, and Why Does It Bend in Water?
Light travels in straight lines called rays . It moves extremely fast and can pass through empty space, air, and some materials like glass and water . When light travels in the same material (like air), it keeps moving straight.
However, when light enters water from air, it slows down . Because of this change in speed, the light ray bends at the surface where air and water meet. This bending of light is called refraction . Refraction is why a straw in a glass of water looks bent and why swimming pools appear shallower than they really are .

🌈 How Does Light Travel, and Why Does It Bend in Water? 💡💧
Light travels in straight lines called rays 🚀. It moves extremely fast and can pass through empty space, air, and some materials like glass and water 🌍. When light travels in the same material (like air), it keeps moving straight.
However, when light enters water from air, it slows down 🐢. Because of this change in speed, the light ray bends at the surface where air and water meet. This bending of light is called refraction 🔍. Refraction is why a straw in a glass of water looks bent and why swimming pools appear shallower than they really are 🏊♀️✨.
