Wave Properties and Light Behavior

The video tutorial covers the basics of waves, including energy transfer, types of waves, and their properties such as crest, trough, frequency, and amplitude. It explains the electromagnetic spectrum, detailing the different types of electromagnetic waves and their uses. The tutorial also discusses how light interacts with objects, affecting color perception, and explores phenomena like reflection, refraction, and diffraction. Additionally, it compares sound and light waves, highlighting their differences and similarities.

What is the main difference between electromagnetic and mechanical waves?
