Follow the sign conventions. Express your answer to three significant figures and include the appropriate units hil = 1- 13.5cmExplanation / Answer
ho= 2.70 cm, f = -125 mm= -.125m , u = 1.50 m ,
1/u + 1/v = 1/f
1/ 1.50 + 1/v = - 1/ 0.125
1/v= - 1/ 0.125 - 1/ 1.50= - ( 1.625 ) / (0.1875)
v = -0.115 m o
b) hi / 2.70 cm = - ( -0.115/1.50)
