Humans cannot detect infrared light because our eyes are only sensitive to a limited range of wavelengths, known as visible light. Infrared light has longer wavelengths than visible light, making it undetectable to our eyes. Specialized equipment, such as infrared cameras, is needed to detect and visualize infrared light.
The light that our eyes can detect is known as visible light.
Yes, some bugs can detect infrared light.
this depends on the situation. normally all one would need is a thermal sensor in order to detect light

Using a black light can help detect semen stains due to proteins in semen reacting to the ultraviolet light. However, for confirmation, additional testing such as a forensic analysis might be needed to definitively identify the presence of semen.
To effectively utilize a plug-in light sensor to automate lighting in your home, first plug the sensor into an outlet near the light you want to control. Adjust the sensitivity and settings of the sensor to detect when it is dark and trigger the light to turn on. Position the sensor in a location where it can accurately detect changes in light levels. Test the sensor to ensure it is working properly and adjust as needed.

Photocells are used in automatic street lights to detect ambient light levels. When it gets dark, the photocell detects the decrease in light and triggers the street light to turn on. This helps in energy conservation by ensuring that the street lights are only on when needed.
An x-ray will be needed to detect a fracture.
