Question

An object is placed 15 cm away from a convex mirror of focal length 45 cm

Answer 1

so what we have to do???

Answer 2

Answer:

C= 90cm so f = 45

also u is -15cm

1/f = 1/v + 1/u

1/45= 1/v +(-1/15)

1/45 + 1/15 = 1/v

1/v = 4/45

v= 45/4

= 11.25

m= -v/u

= -(-11.25)/-15 = 0.75

therefore image is real inverted and diminished. it is also between f,p
