Measuring f for a diverging lens. To measure the focal length of a diverging lens, a converging lens is placed in contact with it. The Sun's rays are focused...
A) The focal length of the diverging lens is equal to the distance between the two lenses
B) The focal length of the diverging lens is equal to the focal length of the converging lens
C) The focal length of the diverging lens is equal to the sum of the focal lengths of the converging lens and the diverging lens
D) The focal length of the diverging lens is equal to the difference between the focal lengths of the converging lens and the diverging lens
