An object of som in length is placed it at a distanceof 20 cm is in front of a a convex miron of radius of carvature 30 cm. Find the position, size and nature.
Answers
Answer:
Radius of curvature (R) = 30 cm
f = R/2 = 30/2 = 15 cm
u = -20 cm,
h= 5 cm.
1/v +1/u = 1/f
1/v = 1/f – 1/u
1/v = 1/15 – 1/-20
v = 8. 57 cm
Image is virtual and erect and formed behind the mirror.
m = -v/u
m = hi/ho
hi/5= 8.57/20
= 0.428
hi = 0.428 x 5 = 2.14cm
Position of Image: Behind the mirror.
Nature of Image: Virtual and Erect.
Size of the Image: Diminished.
Explaination: please mark me as brainliest because I have gave much time to this.
