Hertz and Lenard's observations of light demonstrated that light could exist in two forms: as waves and as particles. This observation challenged classical physics's long-held belief that light was a wave.
Evidence from the experiment:
Hertz observed the same frequency of light regardless of the medium through which it was traveling. This observation contradicted the wave nature of light, which predicted that light waves would bend around obstacles.
Lenard experimented with different materials and found that the frequency of light emitted by a gas was independent of the material. This observation contradicted the particle nature of light, which predicted that light was composed of discrete particles.
Implications of the observations:
These observations provided strong evidence for the dual nature of radiation, which states that light exists as both waves and particles.
This means that light can behave like a wave when it interacts with matter, or like a particle when it interacts with other waves.
The dual nature of radiation has profound implications for our understanding of light and the universe
