What is the frequency of flashes for a standard flashing light?

  1. 50 to 70 flashes per minute

  2. 120 flashes or more per minute

  3. 30 flashes per minute

  4. 100 flashes per minute

The correct answer is: 120 flashes or more per minute

A 50 to 70 flashes per minute is not the frequency for a standard flashing light. The frequency varies based on the type of light and its purpose. C: 30 flashes per minute is too slow of a frequency for a standard flashing light. Again, the frequency can vary based on the purpose of the light. D: 100 flashes per minute is a common frequency for many flashing lights, but it is still not considered the standard. Different lights may have different frequencies. A standard flashing light usually has a frequency of 120 flashes or more per minute. While 100 flashes per minute is a common frequency for many flashing lights, it is not considered the standard. The frequency of a flashing light may vary based on its purpose and type, but generally it is faster than 100 flashes per minute. Therefore, B is the correct answer.
