Light: Reflection and Refraction: Class 10 Science (CBSE) important questions and practice
Light: Reflection and Refraction is chapter 9 of 13 in CBSE Class 10 Science. Below are the topics the paper draws from, the question types that come up again and again, and a free practice test on this chapter alone.
Topics in this chapter
- Reflection by spherical mirrors: concave and convex
- Ray diagrams and image formation by mirrors
- Mirror formula and magnification
- Refraction of light, laws of refraction and refractive index
- Image formation by convex and concave lenses
- Lens formula, magnification and power of a lens
What examiners usually ask
- Draw a ray diagram to show the image formed when an object is placed between F and 2F of a convex lens
- An object 5 cm tall is placed 25 cm from a concave mirror of focal length 15 cm; find the position, size and nature of the image
- State the laws of refraction and define refractive index
Exam tip
Use the New Cartesian sign convention consistently (object distance negative) and state the nature of the image from the sign of v and m; ray diagrams for all six object positions of the concave mirror are commonly asked.
