Lesson: Holography 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 how the phase differences of coherent light waves can be used to produce three-dimensional images.

Students will be able to

define the terms illumination beam, reference beam, and object beam,
describe how a holographic plate records information on the phase differences between waves from different points on the surface of a three-dimensional object,
describe how the appearance of a holographic virtual image depends on the relative positions of reference, illumination, and object beams.
