Question on: WAEC Physics - 2012
An object is placed 10cm from a converging lens of foal length 15cm. Calculate the magnification of the image formed
A
3.0
B
1.5
C
0.6
D
0.3
Ask EduPadi AI for a detailed answer
Correct Option: A
(\frac{1}{v} = \frac{1}{f} - \frac{1}{u})
(\frac{1}{15} - \frac{1}{10} = \frac{2 = 3}{30})
v = 30
but m = (\frac{v}{u} = \frac{30}{10} = 3)
