Today, we are going to discuss regular reflection. Can anyone tell me what happens when light hits a smooth surface?

Exactly! This is what we call regular reflection. It occurs on smooth surfaces, like a mirror, and gives us a clear image. Can anyone think of an example of regular reflection in real life?

Great example! Regular reflection allows you to see your image clearly. Remember the acronym 'MIRRORS' to sum it up: **M**irror **I**mages are **R**egularly **R**eflected **O**n **R**ecent **S**urfaces.

Good question! We will cover that in the next session.

So, to summarize, regular reflection occurs on smooth surfaces, producing clear images. This concept is key in optics.

Let’s move on to diffuse reflection. What do you think happens when light strikes a rough surface?

Exactly! This scattering is what we call diffuse reflection. It occurs on rough surfaces, resulting in unclear images or no distinct image at all.

Excellent question! Diffuse reflection allows us to see objects even when the surface isn't smooth, like when light hits a wall. Remember the mnemonic 'ROUGH' for diffuse: **R**eflection **O**n **U**neven **G**round **H**elps visibility.

Because most surfaces are not perfectly smooth. That's why we can see various textures and surfaces under different lighting conditions, thanks to diffuse reflection.

In summary, diffuse reflection occurs on rough surfaces, scattering light, which allows us to perceive objects in everyday situations.
