Which one of the following devices does not respond to the intensity of light incident on it ?
Text Solution
Verified by ExpertsThe correct answer is:
C
A device that does not respond to the intensity of incident light is the Light Emitting Diode (LED).
LDR (Photoresistor) → Resistance changes with light intensity.
Photodiode → Current depends on incident light.
Solar Cell → Produces electrical energy from light.
LED → Emits light when current passes through it; it does not detect light.
