Understanding Light and Its Properties

The video explores the nature of light, its properties as an electromagnetic wave, and its role in creating colors. It includes a hands-on activity to demonstrate refraction and reflection, explains optical illusions like apparent depth, and discusses phenomena such as dispersion and Rayleigh scattering. The video concludes with a summary of key concepts, emphasizing the relationship between wavelength, frequency, and energy.
