This theory revolutionized our understanding of biology and laid the foundation for modern cell biology.

The photoelectric effect requires light frequency to exceed a threshold value; increasing intensity alone won't eject electrons if frequency is below the threshold.

Nuclear fission is the process in which a heavy atomic nucleus (such as uranium-235) splits into two smaller nuclei, releasing a large amount of energy.
