LDR: Light-dependent resistor

This resistor shows Drop or rise in resistance with respect to incident light on it.

This can be measured by putting it into a voltage divider and reading voltage across it.

When  LDR does not have any incident light on it it shows the highest resistance and vice-versa.

Voltage divider is dividing the total voltage between two resistance.

Resistance is high then the voltage will be higher.
