An object is placed 6.5 cm in front of a converging lens that has a focal length of 14 cm. Which one of the following statements
andreyandreev [35.5K]

Answer:

B) The image is virtual and 12 cm from the lens

Explanation:

u = Object distance =  6.5 cm

v = Image distance

f = Focal length = 14 cm

Lens Equation

\frac{1}{f}=\frac{1}{u}+\frac{1}{v}\\\Rightarrow \frac{1}{f}-\frac{1}{u}=\frac{1}{v}\\\Rightarrow \frac{1}{v}=\frac{1}{14}-\frac{1}{6.5}\\\Rightarrow \frac{1}{v}=\frac{-15}{182} \\\Rightarrow v=\frac{-182}{15}=-12\ cm

Focal length of the lens is -12 cm. The negative sign implies the image is virtual in nature.
