Do stars produce radiant energy?
The most basic property of stars is that their radiant energy must derive from internal sources. Only protons of extremely high energy (many times the average energy in a star such as the Sun) are capable of producing nuclear events of this kind. …
What are four types of radiant energy?
Radiant energy is energy contained in electromagnetic waves. These include visible light, infrared, radio waves, ultraviolet and microwaves.
What are the seven types of radiant energy?
There are seven natural forms of EMR. Gamma rays have the highest energy and shortest wavelength. Then come X-rays, ultraviolet light, visible light, infrared radiation and microwave radiation. Finally, radio waves have the lowest energy and longest wavelength.
What is radiant energy Class 7?
Radiant energy is energy that travels by waves or particles, particularly electromagnetic radiation such as heat or x-rays. An example of radiant energy is the source of energy used in radiation therapy. pls mark as brainliest.
How is energy produced in a star?
Stars produce energy from nuclear reactions, primarily the fusion of hydrogen to form helium. These and other processes in stars have lead to the formation of all the other elements.
What is the source of energy of a star?
Fusion: The energy source of stars. The energy released from the collapse of the gas into a protostar causes the center of the protostar to become extremely hot. When the core is hot enough, nuclear fusion commences. Fusion is the process where two hydrogen atoms combine to form a helium atom, releasing energy.

What is radiant energy class 11?
Energy is emitted or absorbed continuously in the form of radiant energy. These radiations consist of electric and magnetic field acting perpendicular to the direction of propagation of wave. These waves can travel through medium as well as through vacuum.
What is the difference between radiant energy and radiation?
What Do You Mean? Short electromagnetic waves contain more energy than long ones. Radiant energy is the energy of electromagnetic waves. Radiation is the emission of energy as electromagnetic waves. Light energy is a type of radiant energy that can be seen by the human eye. The Sun is the closest star to the planet Earth and radiates light energy.
Does the Sun produce radiant energy?
Yes, the Sun produces a lot of radiant energy, which is transmitted to Earth as light. Plants convert the electromagnetic energy in sunlight into chemical energy for their food, through a process called photosynthesis. Waves of radiant electromagnetic energy can be visible or invisible.
What do stars do with their energy?
Stars spend most of their lives repetitively compressing two hydrogen atoms into a single helium atom – plus a lot of energy, which is released as light and heat. Stars can squeeze various types of atomic fuel together, and it’s through this process that we get almost every element in the universe.
How does radiant energy enter a system?
Radiant energy is a mechanism by which energy can enter or leave a system. For example, while a campfire is burning, the chemical potential energy that is bound within the molecules of the wood is escaping as radiant energy, just like the mechanical energy from clapping hands can escape the system as sound waves.
