Which of the following are true for optical instruments?

(A) A simple microscope is a converging lens of large focal length.
(B) A telescope is used to provide angular magnification of distant objects.
(C) The objective lens of a telescope has a smaller focal length than the eyepiece.
(D) The magnifying power of a telescope is the ratio of the focal length of the objective lens to the focal length of the eyepiece.
(E) A simple microscope is a converging lens of small focal length.

Choose the correct answer from the options given below:

(B), (D) and (E) only

The correct answer is Option (3) → (B), (D) and (E) only

$\text{(A) False. A simple microscope is a converging lens of small focal length, not large.}$

$\text{(B) True. A telescope provides angular magnification of distant objects.}$

$\text{(C) False. In a telescope, the objective has a large focal length and the eyepiece has a small focal length.}$

$\text{(D) True. Magnifying power of a telescope } M=\frac{f_o}{f_e}, \text{ where } f_o=\text{focal length of objective}, f_e=\text{focal length of eyepiece.}$

$\text{(E) True. A simple microscope is a converging lens of small focal length.}$
