Using Light: Reflection and Mirrors

The video tutorial explains the concept of reflection, using examples like a smooth lake surface and a car's rear-view mirror. It describes how light behaves similarly to a bouncing ball, with incident and reflected rays forming equal angles. The law of reflection is introduced, stating that the angle of incidence equals the angle of reflection. The video also covers diffuse reflection, which occurs on irregular surfaces, such as brick walls and the atmosphere, causing light to scatter in various directions.

What is the similarity between light reflection and a bouncing ball?

• Both follow the same path back to the source.

• Both can change color upon impact.

• Both require a smooth surface to bounce.

• Both bounce off surfaces at equal angles.

What are the light rays called that hit a surface?

• Reflected rays

• Incident rays

• Scattered rays

• Refracted rays

According to the law of reflection, what is true about the angles of incidence and reflection?

• They are complementary.

• They are equal to each other.

• They are always different.

• They are supplementary.

What type of reflection occurs on a smooth surface like a mirror?

• Diffuse reflection

• Scattered reflection

• Regular reflection

• Refracted reflection

Why does the atmosphere scatter sunlight?

• Because it is filled with water droplets.

• Because it is filled with gases and dust particles.

• Because it is a smooth surface.

• Because it is a vacuum.
