What is the application of the photoelectric effect in digital cameras?
Generating electricity
Capturing images
Measuring temperature
Detecting gas leaks
Answers (1)
The photoelectric effect is utilized in digital cameras through the use of a photoelectric sensor. This sensor detects light and converts it into an electrical signal, which is then processed to form an image. Therefore, the correct answer is 2) Capturing images.
Option 1) Generating electricity is also a valid application of the photoelectric effect, but it is not directly related to digital cameras. It is used in solar panels to convert light energy into electrical energy.
Option 3) Measuring temperature is not an application of the photoelectric effect. Instead, it is usually accomplished through the use of temperature sensors such as thermocouples or infrared sensors.
Option 4) Detecting gas leaks is also not an application of the photoelectric effect. Gas leaks are typically detected using specialized gas sensors that detect the presence of specific gases in the air.
