    What happens when the night time interrupt with light more than one time? I learned some interesting things in my school lessons and I came to listen to khan academy for a more accurate explanation but this video didn't include them.

      studied this very recently, it actually depends on the last type of light that interrupts the night time. we already know that interruption in night time for short day plants prevent them from flowering but for long day plants, you can expose them to red and far red light more than once but the only condition required for it to flower is that the last light it's exposed to is red light.
