Question 1 Report
A concave mirror can be used to produce a parallel beam of light if a lighted bulb is placed
Answer Details
A concave mirror is a mirror that curves inward, like the inside of a spoon. The property of a concave mirror that allows it to produce a parallel beam of light is its ability to reflect incoming light rays in such a way that they all converge to a single point called the focal point.
When an object is placed between the focus and the pole of a concave mirror, a virtual, upright, and magnified image is formed behind the mirror. However, if a lighted bulb is placed at the focus of a concave mirror, the incoming light rays are reflected parallel to the principal axis of the mirror. Therefore, the correct answer is "at its focus."
