Question

to study effect of intensity of light on an ldr reading ​

Answer 1

Answer:

· A light dependent resistor is prepared from cadmium sulphide. Its resistance depends upon the intensity and duration of light incident on it. ... The intensity of light decreases inversely with increase the square of distance.

Answer 2

An ldr is a device where the resistance varies with change in the intensity of light.

Explanation:

• An ldr stands for a light dependent resistor.
• It consists of cadmium sulphate which can detect light. When the distance between the force of the light and the resistor is increased the resistance also increases.
• The resistance is dependent it on on the distance between the resistor and the instrument.
• The resistance is proportional to the square of the distance between the resistor and the instrument.
