(a)
Interpretation:
Whether
Concept introduction:
Semiconductors are devices that have conductivity intermediate between conductors and insulators and their conductivity gets enhances when doped.
Doped semiconductors are used in commercial electronic devices as diodes, transistors, LEDs, photovoltaic cells. They all differ in their functions that are as follows:
- Diodes convert alternating current to direct current.
- Photovoltaic cells convert sunlight to electricity.
- LEDs act as a light source.
- Transistors amplify an electrical signal in an integrated circuit.
(b)
Interpretation:
The LED that emits green and the LED that emits UV light should be determined.
