Why the charge on the drum in a photocopier disappears when light shines upon it? My solution says that it's because the drum is photosensitive. but what is "photosensitive" property ?

The term "photosensitive" refers to an object's ability to react or respond to light. In the case of a photocopier, the drum is made of a material that is photosensitive, meaning it can be affected by light. When light shines on the drum, it triggers a chemical reaction that causes the charge on the drum to disappear. This is an important property in the functioning of a photocopier, as it allows for the transfer of toner onto the paper, creating a copy of the original document. Essentially, the photosensitive property of the drum is what allows for the photocopying process to occur.
