Heat transfer by radiation occurs in the infra-red part of the electromagnetic wave spectrum, because matter emits and absorbs radiation with that range of frequencies.
This process is called solar radiation. The sun emits energy in the form of electromagnetic waves, which includes heat and light. When this energy reaches the Earth's surface, it warms the planet through the process of solar radiation.
The Earth's heat is dissipated through processes such as conduction, convection, and radiation. Conduction transfers heat through the Earth's crust, while convection involves movement of molten material in the mantle. Radiation allows heat to be released into space.
Radiation from the sun is the primary source of heat for the Earth, warming the planet and maintaining its average temperature. The Earth also emits heat in the form of infrared radiation back into space, resulting in cooling. The balance between incoming solar radiation and outgoing infrared radiation determines the Earth's overall temperature.
Heat is normally transferred to specific areas by means of a 'heat sink' which is usually made of a material with low resistance and high transfer of heat. An example of this can be seen in most computers, the heat sink collects the heat from the processor, and there is (usually) a fan which is near or on the heatsink to remove it from the heat sink, effectively lowering the temperature of the processor.

Another example of an object that transfers heat by radiation is a fireplace.
The word you are looking for is "radiation." The sun transfers heat to the Earth through electromagnetic radiation, including visible light, infrared radiation, and ultraviolet rays.
The three ways are: radiation, conduction, and convection.

Radiation, Conduction, Convection
Radiation transfers heat in the form of rays or waves. This process does not require a medium and can occur through a vacuum. Radiation is responsible for the heat we feel from the sun and from objects that are at a higher temperature than their surroundings.
Radiation transfers heat through electromagnetic waves, while conduction transfers heat through direct contact between particles, and convection transfers heat through the movement of fluid or gas. Radiation does not require a medium to transfer heat, making it effective in vacuum environments like space.
Heat from the sun transfers to Earth through radiation.
Conduction, convection, and radiation are all methods of heat transfer. They are alike in that they involve the movement of heat energy from one object to another. However, they are different in terms of the mechanisms involved: conduction transfers heat through direct contact between objects, convection transfers heat through the movement of fluids, and radiation transfers heat through electromagnetic waves.
There are three types of heat transfers: conduction, convection and radiation. The heat transfer caused by the greenhouse effect is radiation.
Convection and radiation (internally) and radiation (externally).
