Light Reflection Concepts

The video tutorial introduces the concept of reflection, explaining how light bounces back from surfaces. It covers the basic terms related to reflection, such as incident ray, reflected ray, and normal. The two laws of reflection are discussed, emphasizing that the incident ray, reflected ray, and normal lie on the same plane, and that the angle of incidence equals the angle of reflection. The video distinguishes between regular and irregular reflection, using mirrors and paper as examples. It concludes with practical examples and encourages viewers to engage with additional resources.

What is the primary function of a mirror in terms of light?

• To refract light

• To absorb light

• To reflect light

• To transmit light

Which term describes the ray of light that strikes a surface?

• Normal

• Incident ray

• Reflected ray

• Refracted ray

What is the angle between the incident ray and the normal called?

• Angle of reflection

• Angle of refraction

• Angle of deviation

• Angle of incidence

According to the first law of reflection, where do the incident ray, reflected ray, and normal lie?

• On different planes

• On the mirror surface

• On the same plane

• On parallel planes

What does the second law of reflection state about the angles of incidence and reflection?

• They are supplementary

• They are complementary

• They are equal

• They are always different

Do all objects reflect light in the same manner?

• Yes, all objects reflect light the same way

• No, only mirrors reflect light

• No, different objects reflect light differently

• Yes, but only in the dark

What type of reflection occurs on a highly polished surface?

• No reflection

• Diffuse reflection

• Regular reflection

• Scattered reflection

Which type of reflection is characterized by light scattering in different directions?

• Regular reflection

• Irregular reflection

• Focused reflection

• Specular reflection

What happens to a parallel beam of light when it hits a rough surface?

• It gets focused

• It remains parallel

• It gets absorbed

• It gets scattered

Which of the following is an example of an irregular reflector?

• Glass

• Paper

• Mirror

• Water
