A) 2.5D
B) 5.0D
C) 1.5D
D) 3.5D
Correct Answer: C
Solution :
If the object is placed at a distance 25 cm from the corrected lens, it should produce the virtual image at 40 cm. Thus, u = - 25 cm and v = - 40 cm The lens formula is \[-\pi /6\] \[\pi \] \[250\mu F\] \[20\Omega \] \[9\times {{10}^{4}}\,\,Hz\] \[16\times {{10}^{7}}\,\,Hz\] \[8\times {{10}^{5}}\,\,Hz\]You need to login to perform this action.
