Exploring Light (Video & Questions)

The video explores the nature of light, describing it as energy that travels in straight lines. It explains how light interacts with objects through absorption, reflection, and refraction. Absorption occurs with opaque objects, allowing us to see colors. Reflection involves light bouncing off smooth surfaces, like mirrors, and has historical applications. Refraction is the bending of light through different materials, demonstrated by prisms creating rainbows.

What is light primarily described as?

• A type of sound wave

• A form of energy that travels in waves

• A chemical reaction
