Topics Covered in Light – Reflection and Refraction

1. Reflection of Light

Reflection occurs when light returns to the same medium after striking a surface. Students should understand the laws of reflection and how images are formed by mirrors.

Important concepts include:

• Laws of reflection
• Incident ray, reflected ray and normal
• Angle of incidence and angle of reflection
• Regular and diffused reflection

2. Spherical Mirrors

Spherical mirrors have reflecting surfaces that form part of a sphere. They are classified into two main types:

Concave mirror: Its reflecting surface curves inward. Depending on the object’s position, it can form real or virtual images.

Convex mirror: Its reflecting surface curves outward. For a real object, it generally forms a virtual, erect and diminished image.

Students should practice ray diagrams and learn the image characteristics for different object positions.

3. Mirror Formula and Magnification

The mirror formula connects the focal length, image distance and object distance.

Mirror formula:

1/f = 1/v + 1/u

Here:

• f = focal length
• v = image distance
• u = object distance

Magnification for a spherical mirror is:

m = hᵢ/hₒ = −v/u

Here, hᵢ represents image height and hₒ represents object height.

Remember to follow the Cartesian sign convention while solving numerical problems.

4. Refraction of Light

Refraction is the change in direction of light when it passes obliquely from one transparent medium into another because its speed changes.

Important concepts include:

• Refraction through different media
• Bending of light towards or away from the normal
• Incident ray, refracted ray and normal
• Laws of refraction
• Refractive index

5. Refractive Index

The absolute refractive index of a medium is given by:

n = c/v

Here:

• n = absolute refractive index
• c = speed of light in vacuum
• v = speed of light in the medium

Students should understand the relationship between the speed of light and refractive index and practise questions based on this formula.

6. Refraction Through a Glass Slab

When light passes through a rectangular glass slab, it bends at the two surfaces. The emergent ray is generally parallel to the incident ray when the two opposite faces are parallel, although it may be laterally displaced.

Practise labelled diagrams showing the incident ray, refracted ray, emergent ray and normal.

Important Formulas for Class 10 Science

Revise these formulas while preparing your notes:

Concept	Formula
Mirror formula	1/f = 1/v + 1/u
Mirror magnification	m = −v/u
Magnification by height	m = hᵢ/hₒ
Absolute refractive index	n = c/v
Snell’s law	n₁ sin i = n₂ sin r

Use the sign convention and formula appropriate to each question. Practise calculations with correct units and clear working steps.

Important Practice Questions

Attempt these questions after revising the chapter.

1. State the two laws of reflection.
2. Differentiate between concave and convex mirrors.
3. Define the principal focus and focal length of a spherical mirror.
4. Write the mirror formula and explain its symbols.
5. What is magnification? What does its sign indicate?
6. Define refraction of light.
7. State Snell’s law of refraction.
8. Define the absolute refractive index of a medium.
9. Draw a labelled diagram showing refraction through a rectangular glass slab.
10. Solve numerical problems using the mirror formula and refractive index formula.

These are practice questions for revision, not a guarantee of the questions that will appear in an examination.

How to Prepare This Chapter Effectively

Follow these steps for a structured revision:

1. Read the relevant textbook section carefully.
2. Study the handwritten notes and mark important definitions.
3. Practise all prescribed ray diagrams with proper labels.
4. Learn the formulas and apply the correct sign convention.
5. Solve numerical problems step by step.
6. Attempt textbook exercises and previous-year questions where available.
7. Revise mistakes before your examination.

Do not rely only on memorising formulas. Understanding image formation and the direction of light rays will help you solve unfamiliar questions.
