"Washington State Department of Agriculture workers, illuminated by red lamps, vacuum a nest of Asian giant hornets from a tree in Blaine"
Interesting. Why do they use red lamps?
- rory096 6y agoRed light is typically used at night in order to avoid destroying the eye's rhodopsin, which helps with night vision and takes at least 30 minutes of non-exposure to blue light to fully replenish. You'll see pilots and astronomers using red flashlights for this reason. https://en.wikipedia.org/wiki/Rhodopsin https://en.wikipedia.org/wiki/Rhodopsin
- Davidzheng 6y agoI think hornets probably don't react to red light. I think bee researchers also use red lights in labs when extracting bees so they don't become active in the presence of light.
