Question

an object is placed at adistance of 10 cm is front of a convex mirror whose focal length in 5 cm. where is image formed? draw the diagram​

Answer 1

Answer:

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. ∴ Image Distance(v) = 3.33 cm. Hence, the Image is formed on the other side of the Mirror at the distance of 3.33 cm.

Answer 2

Answer:

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,

1/f=1/v + 1/u

=1/5= 1/v + 1/u

= 1/5 = (10−v)/10v

10v=50−5v

15v=50

v= 10/3

so the image distance (v) =3.33cm.

the images from behind

the mirror( virtual, real and dimension)
