Reflection of Light

Reflection occurs when light bounces back from a surface. Students learn about:

• Types of reflection: regular and diffused

• Laws of reflection

• Formation of images by mirrors

• Role of curved mirrors in daily life

Understanding reflection helps students explain common optical phenomena such as image formation and mirrors.

Refraction of Light

Refraction is the bending of light as it passes from one medium to another. Students study:

• Concept of refraction and its causes

• Refraction through lenses and transparent materials

• Effects such as bending of objects in water

• Importance of refractive index

This section explains how light changes direction and its significance in optics.

Applications of Reflection & Refraction

Understanding reflection and refraction has practical applications. Students learn about:

• Uses of mirrors and lenses in daily life

• Optical instruments such as telescopes, microscopes, and cameras

• Corrective lenses for vision defects

• Importance in scientific experiments and technology

This topic helps students relate physics to real-world scenarios.
