Question

If the focal length of a convex lens is 3cm and the object is placed at a distance of 15cm, then where will the image be formed? Draw a ray diagram​

Answer 1

Answer:

i am extremely sorry that i cant upload the ray diagram hope u understand

Explanation:

given:

f=+3cm(convex lens)

u=-15cm

by lens formula

1/f=1/v-1/u

1/3=1/v-(-1/15)

1/3=1/v+1/15

1/3-1/15=1/v

(5-1)/15=1/v

v=15/4

v=3.75

so image will form between f and c

as v>f

andv<2f(2f=c)
