A photocell is in which mode when its output is ON only if light from the source is detected?

Explanation:
Photocells can be configured to respond to light in different ways. When the output turns on only if light from a source is detected, the sensor is being activated by the presence of light itself. This behavior is described as light mode. In contrast, dark mode would have the output turn on in darkness, infrared mode refers to sensing infrared radiation rather than visible light, and passive mode implies no active sensing condition tied to light detection. So, the mode described is light mode.
