Options

A. STATEMENT -`1`is true statement `2` is true,Statement -`2`is a correct explanation for statement -`1`
B. STATEMENT -`1`is true statement `2` is true,Statement -`2`is a not a correct explanation for statement -`1`
C. Statement -`1`is true,Statement -`2`is False
D. Statement -`1`is False ,Statement -`2`is True

Answer

A

Explanation

`100%` of incident light is reflected back into the same medium ,and there is no loss of intensity,while in reflection from mirrors and refraction from lense =s,there is always some loss of intensity ,Therefore ,images formed by total internal refleciton aremuch brighter than those formed by mirrors of lenses.
