To determine the location of the light source in front of a concave mirror, we can follow these steps: ### Step-by-Step Solution: 1. **Identify the Given Information**: - Radius of curvature (R) = 160 cm - Image distance (v) = -70 cm (since the image is formed behind the mirror, we take it as negative for concave mirrors) ...
