The answer is true light is one of the forms of electromagnetic energy. The law of conservation of energy was first formulated by French physicist Antoine Lavoisier in 1789. In this blog post, the author explains the concept of energy and how it can change from one form to another. The idea that light may be a particle was first advocated by Sir Issac Newton, but the idea didnt catch on particularly well until the 19th century, when Albert Einstein revived the view. Later, when detectors were installed at the slits, it was observed that each photon only passed through one of the slits, which is again a particle behavior, rather than a wave-like behavior. How well do you understand the article above! Yes, energy is the ability to do work. c. A packet of light energy is called a photon. photosynthesis. This is because the sun emits a huge amount of energy in the form of light and heat, which is then absorbed by Earths atmosphere and oceans.
