Question

III. Procedure: A person whose height he = 1.8 m was standing at various object distances (do) in front of a large convex security mirror. The object distances were measured by a measuring tape. The corresponding image heights (hi) were measured by a ruler. The results of the experiment are indicated in the raw data table below. do (m) hi (m) focal length (m) magnificati di (m) on 100 0.56

Answer 1

Summary: I applied mirror formula to calculate the focal length of mirror.

he = 1.8m magnification ha 70.56M hi ha 0.56 m liom m = 0.311 also, ms 0.311 / « (position of images u {position of objed (di m = (مام) 0.311 - di loom di - 0.311 X100m di 340 m minor formula to the F. + 어 di do f 1 CA m.3۔ loom # 31. lxloo -100+ 3.1.1.)" - - 45.16 m
