the intensity of blue light is lowered will the reading on the ammeter shows a reading which indicates an electric current

To determine if the reading on an ammeter will indicate an electric current when the intensity of blue light is lowered, you need to understand how electric current and light intensity are related.

Electric current is the flow of electric charge through a conductive medium, such as a wire. It is typically measured using an instrument called an ammeter.

On the other hand, light intensity refers to the amount of light energy present per unit area or per unit time. In the context of your question, "lowering the intensity of blue light" means reducing the amount of blue light present.

The presence of blue light alone does not directly cause an electric current to flow in a wire. Instead, for an electric current to exist, you typically need a complete circuit that includes a power source (such as a battery) and a closed loop pathway for the electrons to flow through (usually a wire).

If the intensity of blue light is lowered, it should not directly impact the reading on an ammeter without any other changes to the circuit or the behavior of the light source.

However, it is worth noting that in some cases, a decrease in light intensity can affect the behavior of certain electrical components, such as photodiodes, solar cells, or light-dependent resistors. These components have a dependence on light intensity, and their behavior can change when the light intensity they are exposed to is altered.

To sum up, if you are only considering a typical wire connected to an ammeter, lowering the intensity of blue light should not directly affect the reading on the ammeter, as it primarily measures electric current flow and not light intensity.
