Class 10 Science Chapter 9 MCQ : Light – Reflection and Refraction MCQs Quiz
Chapter 9, Light – Reflection and Refraction, explores the phenomena of light interacting with surfaces. The chapter is divided into two main sections: Reflection and Refraction. In the reflection section, students learn about the laws of reflection, types of spherical mirrors (concave and convex), mirror formula, and magnification. The refraction section explains the bending of light (Snell’s Law), the concept of refractive index, and the behavior of light through rectangular glass slabs and prisms. The chapter concludes with a detailed study of Lenses (convex and concave), their image formation, lens formula, and the concept of the power of a lens. Understanding these concepts is crucial for solving the numerical problems often found in the Class 10 Science Chapter 9 Quiz.
Conclusion
Mastering Light – Reflection and Refraction is essential for scoring well in the Physics section of your Class 10 Board exams. By attempting this Class 10 Science MCQs Quiz, you have tested your ability to recall formulas, understand ray diagrams, and apply the laws of physics. Regular practice of these Light Reflection and Refraction Class 10 MCQs will help you memorize sign conventions and increase your speed in solving numerical problems.

FAQs on Class 10 Science Chapter 9 MCQ : Light – Reflection and Refraction MCQs Quiz
- State the First Law of Reflection.
The First Law of Reflection states that the angle of incidence is equal to the angle of reflection \( $\angle i = \angle r \). - What is the focal length of a convex mirror?
The focal length of a convex mirror is positive, as the focus lies behind the mirror. - Define the term “Refractive Index”.
The refractive index of a medium is the ratio of the speed of light in a vacuum to the speed of light in that medium. It measures the bending of light when it passes from one medium to another. - What is the SI unit of the Power of a Lens?
The SI unit of the power of a lens is Dioptre (D). - What is meant by the “principal focus” of a concave mirror?
The principal focus of a concave mirror is a point on the principal axis where light rays parallel to the principal axis converge after reflection. - Which lens is used to correct myopia (near-sightedness)?
A concave lens (diverging lens) is used to correct myopia. - Write the formula for the Magnification (m) of a mirror.
The formula for magnification is \( m = -\frac{v}{u} = \frac{h_i}{h_o} \), where \( v \) is image distance, \( u \) is object distance, \( h_i \) is image height, and \(h_o \) is object height. - What happens to the speed of light when it enters a glass slab from air?
When light enters a glass slab from air, its speed decreases because glass is an optically denser medium than air. - Define the “Lens Formula”.
The lens formula relates the object distance \( u \), image distance \( v \), and focal length \( f \) of a lens: \( \frac{1}{v} – \frac{1}{u} = \frac{1}{f} \). - What is Snell’s Law of Refraction?
Snell’s Law states that the ratio of the sine of the angle of incidence to the sine of the angle of refraction is constant for a given pair of media \(\frac{\sin i}{\sin r} = \text{constant} \).
