Lesson: Blackbody Radiation 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 describe the change with temperature of an ideal blackbody’s color and explain how this shows the quantization of light.

Lesson Plan

Students will be able to

define and recognize cavity modes for electromagnetic waves,
compare graphical representations of radiation spectra corresponding to quantised and continuous distributions of wavelengths of blackbody radiation,
use the formula to relate the energy, frequency, and number of quanta emitted by a blackbody.
