Light and Shadow

The video tutorial explores the sun's brightness, its distance from Earth, and how sunlight consists of different colors. It discusses the heat from the sun, the importance of sunscreen, and how sunlight can cause evaporation. The Earth's rotation leads to day and night cycles, with shadows forming when objects block light. The moon reflects sunlight at night, while stars twinkle but provide little light. Natural light sources like the sun and moon are contrasted with man-made lights such as lamps and headlights. The video encourages viewers to experiment with light and shadows using a flashlight.
