a) f=+20.0 cm, s =48.0 cm and h = 10.0 cm ( 3 significant figures in each number) determine using ray tracing method only (atleast 3 rays): s', h' and m (by 2 different methods) Do not use lens equation (it will not count). Use a 8.5" x 1 1" sheet and use sharp pencil and rulers (do not hand draw). b) f=+20.0 cm, s =12.0 cm and h = 6.00 cm determine using ray tracing method only (atleast 3 rays): s', h' and m (by 2 different methods) Do not use lens equation (it will not count). Use a 8.5" x 1 1" sheet and use sharp pencil and rulers (do not hand draw)
