Light energy has been observed and studied by humans since ancient times. The Ancient Greek philosopher Empedocles was one of the earliest to propose that light travels in straight lines. The concept of light energy has evolved over centuries through the work of scientists such as Isaac newton and Albert Einstein.
Light does not have mass. It is a form of energy.
One of light's defining characteristics is that it does not have mass; it is instead pure energy. To answer your question, no one discovered it because it has been proven to be false.
The mathematical relationship of the change of mass to energy was discovered by Albert Einstein with his famous equation E=mc^2, where E represents energy, m represents mass, and c is the speed of light. This equation revolutionized the field of physics by showing that mass and energy are interchangeable.
Various scientists have made contributions to the understanding of sound, heat, and light energy. For sound energy, Ernst Chladni conducted pioneering work on acoustics in the 18th century. Joseph Fourier and James Prescott Joule were instrumental in advancing the understanding of heat energy. In the case of light energy, key figures include Isaac Newton, who studied the behavior of light, and Albert Einstein, who developed the theory of the photoelectric effect.
Planck in his formula E = hf.This was measured by experimenters long before Planck. Einstein's paper on the photoelectric effect explained the observations, Planck later quantified it. Not sure who did the first experiments that discovered the effect.
Wood is the first discovered primary energy source. Some believe that Solar energy (as heat caused by sun light) is the first discovered primary energy source.
Einstein
Niels Bohr discovered that the light released by atoms of gases is related to the energy of electrons. He proposed the atomic model that states electrons orbit around the nucleus in discrete energy levels, which explains the different light emissions observed from atoms.
The term "photosynthesis" was first coined by the scientist Jan Ingenhousz in 1779. Ingenhousz's experiments on plants helped to uncover the process by which they convert light energy into chemical energy.
He discovered that light energy is important for photosynthesis. AD 1845

Sir W. Crookes discovered the Properties of Light in 1879.
UV Light was discovered by Johann Wilhelm Ritter, in 1801
biomass energy was first discovered in the mid 1800's
