Path Difference

The Path Difference and Wavelength Video Tutorial develops the mathematical logic by which the path difference for two waves meeting up at an anti-nodal or nodal line is related to the wavelength. Numerous examples, illustrations, and animations assist in the explanations.

The video lesson answers the following questions:

1. What is path difference and how is it related to the wavelength for points on antinodal and nodal lines?
