Eclipses and Celestial Alignments

The video tutorial explains the phenomena of lunar and solar eclipses, detailing how they occur when celestial bodies align in a straight line. It covers the different types of lunar eclipses—total, partial, and penumbral—and describes how the Earth's shadow affects the moon's appearance. Similarly, it explains solar eclipses, including total, partial, and annular types, and how the moon's shadow impacts the Earth's view of the sun. The tutorial concludes with a review and practice questions to reinforce understanding.
