Question

3. Write all the sign conventions for spherical mirrors green​

Answer 1

Answer:

Explanation:

Sign conventions for spherical mirrors. (i) All the distances are measured from the 'P' (pole) of the mirror. (ii) Distances measured in the direction of incident ray are taken as positive. (iii) Distances measured opposite to the direction of incident ray are taken as negative

Answer 2

Answer:

Sign conventions for spherical mirrors:

(i) All the distances are measured from the 'P' (pole) of the mirror.

(ii) Distances measured in the direction of incident ray are taken as positive.

(iii) Distances measured opposite to the direction of incident ray are taken as negative.

According to the sign convention, the distances towards the left of the mirror are negative. Since as object is always placed to the left side of a mirror, therefore, the object distance (u) is always negative.
