List the three major categories of photodetectors.
Expert Solution & Answer
To determine
The three major categories of photodetectors.
Explanation of Solution
Photodetectors:
Photodetectors are sensors widely used in today’s industries to sense the presence of objects without having the need to make physical contact with the object being sensed. The photodetectors operate at speeds that are much higher and cannot be tolerated by the mechanical contact switches.
Photodetectors can be categorized into three major types as follows:
- Photovoltaic.
- Photoemissive.
- Photoconductive.

1. Two long rods of the same diameter-one made of brass (k=85w/m.k) and
the other made of copper (k=375 w/m.k) have one of their ends inserted
into a furnace (as shown in the following figure). Both rods are exposed to
the same environment. At a distance of 105 mm from the furnace, the
temperature of the brass rod is 120°C. At what distance from the furnace
will the same temperature be reached in the copper rod?
