A blue light flashlight is typically used for detecting stains, counterfeit money, and forensic investigations.
Your flashlight may have turned blue due to a few possible reasons. One common explanation is that it uses a blue LED bulb, which can give off a blue light. Alternatively, if the flashlight has a colored lens or filter, it could also emit a blue hue. Lastly, if the flashlight is malfunctioning or the batteries are low, it might produce an unusual color of light.
The white flashlight beam was split into various colors when passed through the filter, as the filter absorbed certain wavelengths of light and allowed others to pass through, resulting in a colored beam.
