lal distance for vision.hat is the angle of incidence of a ray if the reflected ray is at an anofgle13.90°o to the incident ray? |

Answer» Iftheanglebetween theincident rayandreflected rayis90°, theangleofreflectionis half of90° i.e., 45° . Always, theangle of incidence= theangleofreflection. This means that theanglewhich the normal makes with theincident rayis the same as theanglewhich the normal makes with thereflected ray. |
