Board Exam Special | Light Numericals | Nature of Mirror, Focal Length & Image Height | CBSE 2026

Описание: Class 10 Physics | Mirror Numericals | Nature of Mirror, Focal Length & Image Height | CBSE Boards

In this video, we solve an important CBSE Class 10 Physics numerical based on image formation by spherical mirrors.
We determine the nature of the mirror, calculate its focal length, find the height of the image, and identify whether the image is erect or inverted — all explained step-by-step using sign convention and mirror formula.

📘 Question Covered:
The image of a candle flame placed 30 cm from a mirror is formed on a screen 60 cm in front of it. Identify the mirror type, find focal length, calculate image height, and state image orientation.

✅ Perfect for board exam preparation
✅ Concept clarity + numerical solving approach
✅ Useful for last-minute revision
