Two converging lenses are separated by 27.0 cm. The focal length of each lens is 8.90 cm. An object is placed 33.0 cm to the lef

Ymorist [56]

Answer:

1/i + 1/o = 1/f thin lens equation

i = 33 * 8.9 / (33 - 8.9) = 12.2 cm to right of first lens

27 - 12.2 = 14.8 cm to left of second lens

i = 14.8 * 8.9 / (14.8 - 8.9) = 22,3 cm to right of second lens
