Light, Shadows and Reflections

This lesson teaches you that light is a form of energy. It tells you that tiny energy packets of light are called photons. It is the visible part of electromagnetic radiation having a wavelength of 400 to 700 nanometers and you can see the objects around you with the reflection of light; that is when light strikes the object and reaches our eyes, we see the object. Some of the topics covered are transparent , opaque and translucent objects, shadows, pinhole camera mirrors and reflection.
