Question
Of the possible statements that parallel rays are brought to a focus by a 1) concave mirror, 2) convex mirror, 3) converging lens, 4) diverging lens, the correct answer isGroup of answer choices1 and 2.3 and 4.1 and 3.2 and 3.2 and 4.
Solution
The correct answer is 1 and 3. Parallel rays are brought to a focus by a concave mirror and a converging lens.
Here's why:
-
A concave mirror, also known as a converging mirror, reflects light inward to one focal point. It is called a "converging mirror" because it converges the light that strikes it.
-
A converging lens, also known as a convex lens, bends parallel incoming light rays inward to meet at a single point. This is why it's called a "converging lens" - it converges the light that passes through it.
On the other hand, a convex mirror and a diverging lens scatter incoming parallel light rays outward, so they do not bring rays to a focus.
