Question

2.An object is placed at a distance of 10 cm from a convex mirror of focal length 5 cm. a. Draw a ray diagram showing the formation b. state two characteristics of the image formed​

Answer 1

Explanation:

this is the ans. calculatation can be somewhat wrong but the ray diagram is absolutely correct.

Answer 2

Object Distance(u) = 10 cm. (negative)

Focal length of the lens (f) = 5 cm.

We know, convex mirror always forms the virtual, upright and diminished.Also, Object distance in the convex mirror is always negative where as Image distance and focal length are positive.

Now, Applying the Mirror's Formula,

f

u

=

1

=

10v

(10−v)

10v=50−5v

15v=50

v=

10

so the image distance (v) =3.33cm.
