Reflect

When light or sound waves bounce off a surface, it is called reflection. Reflection of light is how we are able to see objects. When light strikes an object, it can be reflected, absorbed, or transmitted. The reflected light enters our eyes, allowing us to see the object. The angle at which the light hits the surface is equal to the angle at which it is reflected, according to the law of reflection.

Key Concepts

1. Reflection of light
2. Law of reflection
3. Sound reflection

Study Tips

• Understand the Law of Reflection: The angle of incidence is equal to the angle of reflection. Remember that the incident ray, the reflected ray, and the normal to the surface at the point of incidence all lie in the same plane.
• Practice with mirrors: Use mirrors to observe reflection of light. Observe how the angle at which light hits the mirror is equal to the angle at which it is reflected.
• Explore sound reflection: Understand how sound waves can also reflect off surfaces. Experiment with sound and observe how it reflects off different materials.
