Class 10 CBSE Physics Chapter: Light (Spherical Mirrors) Questions to Ponder Upon.

1. How are images formed by spherical mirrors?

   • Images are formed by the reflection of light.

2. How can we locate the image formed by a concave mirror for different positions of the object?

   • By drawing two rays:

     • A ray parallel to the principal axis reflects through the focus (F).

     • A ray passing through F reflects parallel to the principal axis.

3. Are the images formed by a concave mirror real or virtual?

   • Real and inverted if the object is beyond F.

   • Virtual and upright if the object is between F and P.

4. Are the images formed by a concave mirror enlarged, diminished, or of the same size?

Object Position	Image Size	Nature
At Infinity	Diminished	Real, Inverted
Beyond C	Diminished	Real, Inverted
At C	Same Size	Real, Inverted
Between C & F	Enlarged	Real, Inverted
At F	Highly Enlarged	Real, Inverted
Between F & P	Enlarged	Virtual, Upright

5. How does the image change as the object moves from infinity to the pole in a concave mirror?

   • At infinity → Image is highly diminished at F.

   • Beyond C → Image is diminished and between C & F.

   • At C → Image is same size at C.

   • Between C & F → Image is enlarged and beyond C.

   • At F → Image is highly enlarged at infinity.

   • Between F & P → Image is enlarged, virtual, and behind the mirror.

Convex Mirror (Diverging Mirror)

6. How are images formed by a convex mirror?

   • The reflected rays appear to diverge from a virtual focus behind the mirror, forming a virtual image.

7. Are the images formed by a convex mirror real or virtual?

   • Always virtual and upright.

8. Are the images formed by a convex mirror enlarged, diminished, or of the same size?

Object Position	Image Size	Nature
At Infinity	Highly Diminished	Virtual, Upright
Anywhere	Diminished	Virtual, Upright

9. Why do convex mirrors always form virtual and diminished images?

   • Because reflected rays diverge, and the image forms behind the mirror, appearing smaller and upright.

10. Where are convex mirrors used in real life, and why?

    Used in rear-view mirrors of vehicles and security mirrors in stores because they provide a wide field of view and always show upright images
