Select two phenomena for which classical mechanics was unable to explain experimental results.

Question: Select two phenomena for which classical mechanics was unable to explain experimental results.

Classical mechanics failed to explain two key phenomena: blackbody radiation and the photoelectric effect. The "ultraviolet catastrophe" predicted by classical theory suggested that blackbodies would emit infinite energy at high frequencies, which contradicted experimental observations. Max Planck resolved this by introducing quantized energy levels, leading to quantum mechanics. Similarly, the photoelectric effect couldn't be explained by classical mechanics, which predicted that light's intensity should affect electron ejection from metals. Albert Einstein's explanation, proposing that light consists of photons with quantized energy, provided the correct understanding and further supported the development of quantum mechanics.
