Lesson: Radiation Pressure on Perfectly Reflective Surfaces Physics • Third Year of Secondary School

Join Nagwa Classes

Attend live Physics sessions on Nagwa Classes to learn more about this topic from an expert teacher!

In this lesson, we will learn how to calculate the pressure exerted on an object by light that is reflected by it.

Students will be able to

recognize that light exerts a pressure,
recognize that the pressure exerted by light is greater if the light is reflected than if it is absorbed,
use to find the pressure exerted by light of a given intensity that is reflected off a surface,
use to find the force exerted by light of a given intensity that is reflected off a surface with area .
