MCQ

This question has Statement $-1$ and Statement $-2$. Of the four choices given after the Statements, choose the one that best describes the two Statements.

Statement $1$ : Very large size telescopes are reflecting telescopes instead of refracting telescopes.

Statement $2$ : It is easier to provide mechanical support to large size mirrors than large size lenses.

A
Statement $- 1$ is true and Statement $-2$ is false.
B
Statement $-1$ is false and Statement $-2$ is true
✓
Statement $- 1$ and statement $-2$ are true and
Statement $-2$ is correct explanation for statement $-1$
D
Statements $-1$ and statement $-2$ are true and
Statement $-2$ is not the correct explanation for statement $- 1$

✓

Answer

Correct option: C.

Statement $- 1$ and statement $-2$ are true and
Statement $-2$ is correct explanation for statement $-1$

c
One side of mirror is opaque and another side is reflecting this is not in case of lens
hence, it is easier to provide mechanical support to large size mirrors than large size lenses. Reflecting telescopes are based on the same principle except that the formation of images takes place by reflection instead of refraction.
