RADIATION PRESSURE Meaning and
Definition
-
Radiation pressure refers to the force exerted on an object due to the transfer of momentum from electromagnetic radiation. It is a phenomenon occurring when light or any other form of electromagnetic radiation interacts with matter. As radiation is made up of photons, which carry both energy and momentum, these properties can be transferred to particles they encounter.
The magnitude of radiation pressure depends on various factors, including the intensity of the radiation, the surface area of the object, and the properties of the material interacting with the radiation. The pressure exerted is proportional to the energy flux (power per unit area) of the radiation and the reflection or absorption characteristics of the material.
Radiation pressure plays a significant role in various scientific fields, including astrophysics, where it contributes to the dynamics of stars and other celestial bodies. For example, it can initiate stellar wind and support the structure of interstellar clouds. In addition, radiation pressure is relevant in laser technology, particularly in applications such as laser propulsion and laser cooling.
Understanding radiation pressure is crucial because it can have significant impacts on the motion, stability, and behavior of objects and particles when exposed to electromagnetic radiation. By studying and quantifying this force, scientists can better comprehend and manipulate the interaction between radiation and matter, leading to advancements in diverse areas of physics, engineering, and materials science.

Etymology of RADIATION PRESSURE
The word "radiation" originated from the Latin word "radiare", which means "to emit rays". It was first used in the late 17th century to describe the emission and propagation of electromagnetic waves or particles. The term "pressure" comes from the Latin word "pressura", meaning "act of pressing". It refers to the force exerted per unit area when an object comes into contact with another object or medium.
The combination of "radiation" and "pressure" forms the term "radiation pressure", which refers to the force exerted by electromagnetic radiation on a surface or object. The concept of radiation pressure was introduced in the late 19th century by scientists studying the behavior of light and its interaction with matter.
