A photo plate is usually a glass, or metal plate, coated with light sensitive chemicals.
Until used it was kept in the dark. It was placed in the camera and exposed to the light of the scene, then removed, and stored in the dark, until it could again be chemically treated to reveal and fix the image on the plate.
The glass plates produced images that could later be used to produce a copy of the image printed on paper by shining a light through them. Metal plates produced the image on the plate itself. They could be the end result, or be used in specific printing techniques to make copies in a printing press.
The metal and glass plates were replaced by plastic film, and now the film has been replaced with electronic sensors.
Even the term photo plate has been replaced with the term photo mask.

How do photovoltaic cell systems work?
In photo voltaic cells there copper plate and on this plate there is a layer of cupprous oxide layer. On this cuprous oxide layer again there is a thin layer of silver.When light having the threshold frequency is incident on the silver layer it is focussed on the cuprous oxide layer and the electrons on this layer are ejected out and pushed on to the copper plate.Here the copper plate acts as an anode and hence the flow of electrons takes place which constitutes the electric current. The flow of electric current can be observed by coonecting a galvanometer in the circuit attached from silver layer to copper plate. The use of silver layer is that it will stop the ejection of electrons out from it. And this is the photo cell used most widely.It costs 28-30 Rs

What is the moment of inertia of a rectangular plate?
The moment of inertia of a rectangular plate is a measure of its resistance to rotation. It depends on the mass distribution and dimensions of the plate. The formula for the moment of inertia of a rectangular plate is (1/12) mass (length2 width2), where mass is the total mass of the plate, length is the longer side of the plate, and width is the shorter side of the plate.
