How does the frequency of indoor lighting affect photography under different shutters?

Only old-fashioned fluorescent lamps, tubes, loop tubes and other light sources with strobes have requirements for shutters. The strobe of old fluorescent lamps is the frequency of alternating current, 50hz, which is invisible to human eyes. However, if the camera shutter is higher than 1/50s or shooting with a flash, sometimes a half-bright and half-dark photo will be taken, so the shutter should be lower than 1/50s.

In addition, any light source will not affect the shutter, only the color temperature, which can be adjusted later.
