Free Electrons Blue light high frequency Animation

The higher energy blue light ejects electrons with higher kinetic energy compared to the green light. The scientists observed that if the incident light had a frequency less than a minimum frequency ‍ , then no electrons were ejected regardless of the light amplitude.
