Question

Problem 7:  Your camera’s zoom lens has an adjustable focal length ranging from 55 to 150 mm.

Part (a) What is the maximum power of the lens, P_max, in diopters?
Numeric   : A numeric value is expected and not an expression.
P_max = __________________________________________


Part (b) What is the minimum power of the lens, P_min, in diopters?
Numeric   : A numeric value is expected and not an expression.
P_min = __________________________________________

Problem 8:  A camera with a 50.0 mm focal length lens is being utilized to photograph a person standing 4.25 m away.

Part (a) How far, in centimeters, must the film be from the lens?
Numeric   : A numeric value is expected and not an expression.
d_i = __________________________________________


Part (b) If the film is s = 36.0 mm high, what percent of the height of the film will a 1.25 m tall person take up?
Numeric   : A numeric value is expected and not an expression.
|h_o|/s (%) = __________________________________________
