Lesson: Two-Slit Interference Physics • Second 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 positions of points of maximum and minimum intensity in interference patterns generated by double slits.

Lesson Plan

Students will be able to

use the formula to calculate angle, wavelength, slit spacing, and order number in two-slit interference patterns,
use the formula to calculate distances between fringes in two-slit interference patterns,
compare calculated distances between fringes using and using trigonometry.
