Photons
The photoelectric effect is a quantum electronic phenomenon in which electrons are emitted from matter after the absorption of energy from electromagnetic radiation such as x-rays or visible light.
Isaac Newton believed that light was made up of tiny particles called corpuscles. These corpuscles were thought to be emitted by a light source and traveled in straight lines until they interacted with an object.
A flashlight transforms electrical energy into light energy and a small amount of heat energy. The electrical energy powers the light bulb, which then emits light energy to illuminate its surroundings.
The relation between the energy (E) of a photon and the frequency (v) of its associated electromagnetic wave is called the Planck relation or the Planck--Einstein equation:E = hvh is the Planck constant which as a value of about 6.626 * 10-34 J*s (a very very small number)
Only a small amount of the light energy from the sun is used during photosynthesis because plants can only absorb specific wavelengths of light (mainly blue and red light) for the process of photosynthesis. Green light is reflected and not utilized. Additionally, not all the absorbed light energy is converted into chemical energy due to limitations in the efficiency of the photosynthetic process.

The term for the small packets of energy emitted from light is called photons.
The term for the small packets of energy emitted from light is photons. Photons are the basic unit of light and possess characteristics of both particles and waves. They carry energy and momentum and are responsible for electromagnetic interactions.

The proportion of light energy depends on the type of light source and its efficiency. In general, only a small fraction of the total energy emitted by a light source is in the form of visible light that we can see, with the rest being emitted as other forms of electromagnetic radiation such as infrared or ultraviolet light.
Storing energy in small packets allows for flexibility in usage and distribution, making it easier to match supply with demand. It also increases efficiency by minimizing energy losses during transmission and storage. Additionally, small energy packets can be easily integrated into existing infrastructure and support decentralized energy systems.
light is made up of small energy packets known as photons which are massless and as gravity depends on the mass of the particle therefore there is no gravitational force applied on or applied by a beam of light.
Not quite sure what you mean with "thermal light".* Light, and other electromagnetic waves, come in small "packets", or particles, called "photons" in this case. * Electrical energy is carried by charged particles, for example electrons, holes, or ions.
in the terms of photons because energy comes from sun in small packets called photons.
The photoelectric effect is a phenomenon where electrons are emitted from a material when it is exposed to light or other electromagnetic radiation. This effect played a crucial role in the development of quantum mechanics and demonstrated the particle-like behavior of light.
