Did Planck think that light was a particle or a wave?

Planck made this quantization assumption five years before Albert Einstein hypothesized the existence of photons as a means of explaining the photoelectric effect. At the time, Planck believed that the quantization applied only to the tiny oscillators that were thought to exist in the walls of the cavity (what we now know to be atoms), and made no assumption that light itself propagates in discrete bundles or packets of energy. Moreover, Planck did not attribute any physical significance to this assumption, but rather believed that it was merely a mathematical device that enabled him to derive a single expression for the black body spectrum that matched the empirical data at all wavelengths.
The Planck constant, denoted as h, is a fundamental physical constant that relates the energy of a photon to its frequency. It is approximately 6.626 × 10^-34 joule-seconds.
Light particles, also known as photons, are elementary particles that make up electromagnetic radiation, including visible light. They have zero mass and travel at the speed of light.
The Planck constant is used to calculate the energy of a single photon based on its frequency. It provides a way to understand the discrete nature of light particles and their interactions with matter.
The Planck constant is important because it is a fundamental constant in quantum mechanics and has applications in various fields, including physics, chemistry, and engineering. It allows us to understand the behavior and interactions of light particles at a subatomic level.
The Planck constant was first introduced by German physicist Max Planck in 1900 as a way to explain the blackbody radiation spectrum. It was later refined and experimentally determined by Albert Einstein in 1905 through his work on the photoelectric effect.
