1. Question on the masurment:

a) is the likeness plentiful or sunk when s > 2 f ? is the likeness plentiful or sunk when s < 2 f ?


b) is the likeness construct or inverted ? is the likeness existent or implicit ? why?


page 96

2.Explain why control a unwandering disunion betwixt the end and the mitigate (i.e., s+ s’ is unwandering), there are

two positions of the lens at which the likeness controlmed on the mitigate are in foucs (disencumbered likeness).


3. A lens controlms an likeness of an end. the objet is 16 cm from the lens. The likeness is 12 cm from the lens on the similar party as the end. 

(a)what is the focal prolixity of th lens?? is the lens converging or diverging ?

(b)if the end is 8.5 mm high, how high is the likeness? is it construct or inverted?

(c)DRAW a principle-ray diagram.
