Identify from the following the ray diagram which shows the correct path of the reflected ray for the ray incident on a concave mirror as shown:
Step 1: Understanding the ray diagram. A concave mirror forms an image that is reflected in a path determined by the focus (F) and the center of curvature (C). The correct ray diagram will show the reflected ray passing through the focus or focal point.
Step 2: Analyzing the options. - Option (C) depicts the correct reflected ray path for the concave mirror.
Step 3: Conclusion. Thus, the correct answer is option (C). {10pt}
In the adjoining figure, \( AP = 1 \, \text{cm}, \ BP = 2 \, \text{cm}, \ AQ = 1.5 \, \text{cm}, \ AC = 4.5 \, \text{cm} \) Prove that \( \triangle APQ \sim \triangle ABC \).
Hence, find the length of \( PQ \), if \( BC = 3.6 \, \text{cm} \).
