In this amount, you get individualize the redress interspace the imaging flatten should be from the lens ce an design at a undeniable interspace to be in centre. Assume the diluted lens design discussed in exhortation ce a camera with a focal prolixity of 35mm. An design in the show get be in centre when full the rays from the design that by through the lens meet at the similar summit on the imaging flatten.
What should be the interspace from the lens to the imaging flatten ce an design that is :
a)1m from the camera?
b) 100m from the camera?
The cemula ce diluted lense
1/p + 1/q = 1/f
f – focal prolixity of the lense
p – interspace among the lense and the design
q – interspace among the lense and the picture.
a) p = 1m = 1000 mm f= 35 mm
q = 1/(1/f-1/p) = (1/(1/35 – 1/1000))
= (1/(0.028 – 0.001)
= 37.03 mm
b) p = 100m = 100000 mm f= 35 mm
q = 1/(1/f-1/p) = (1/(1/35 – 1/100000))
= (1/(0.02857 – 0.00001)
= 35.01 mm
