Reflection and its Types: A Quiz Session

The video revisits the concept of reflection, explaining specular and diffused reflection. It highlights that surfaces perceived as flat have irregularities affecting reflection. The video explains how light's wavelength influences reflection type and discusses polishing surfaces to enhance specular reflection. A quiz follows, testing knowledge on reflection, angles, and light behavior. The video concludes with a channel promotion for moral values.

What are the two types of reflection discussed in the video?

• Specular and diffused reflection

• Simple and complex reflection

• Direct and indirect reflection

• Internal and external reflection

Why do some surfaces that appear flat still show specular reflection?

• Because they are perfectly flat

• Because the irregularities are smaller than the wavelength of light

• Because they are made of a special material

• Because they are polished regularly
