Answer:Therefore, the film in a camera must be placed at a distance of 0.0358m, 3.58cm 0r 38.5mm depending on the unit.
Step-by-step explanation:
From the question, we have that,
Focal length of the lens, f = +35 mm = 35/ 1000 = 0.035m
The Object distance of the flower, u = 1.50m
The image distance, v = ?
. Using lens formula as, we have that
1/f = 1/u + 1/v
where f= the focal length
u =the object distance
v=image distance
1/ 0.035 = 1/1.50 +1/v
1/v = 1/0.035- 1/1.50
=28.57- 0.667
=27.903
1/v= 27.903
v = 1/27.903
v= 0.0358 m
Therefore, the film in a camera must be placed at a distance of 0.0358m
