David was amazed when he saw shiny pots because:

• They emit their own light.

• The Law of Reflection causing light to bounce off.

• They absorb all light except a specific color.

• They refract light towards our eyes.

Hey there! Aria, Olivia, and Priya are exploring computer graphics and want to know how realistic lighting effects are achieved. Can you help them understand by answering this question?

• Light scattering through a medium.

• Light bending as it travels through different materials.

• Light rays bouncing off virtual objects.

• Light absorbing into different surfaces.

Hey there! Ava, Anika, and Harper are exploring the wonders of fiber optic cables. Can you tell them which phenomenon allows light to travel long distances with minimal loss?

• Refraction

• Reflection

• Total internal reflection

• Diffraction

Hey there! In the Law of Reflection, what does the term "normal" refer to?

• Noah says it's the incoming ray of light.

• Abigail thinks it's a line perpendicular to the reflecting surface at the point of contact.

• Priya believes it's the reflected ray of light.

• Or maybe it's the path the light takes after reflecting?

During a science experiment, Evelyn and Jackson were testing the Law of Reflection. What happens to the angle of incidence (θi) and the angle of reflection (θr) when light strikes a smooth surface?

• θi is always larger than θr.

• θi is always smaller than θr.

• θi is completely unrelated to θr.

• θi is equal to θr.

Charlotte is playing with different surfaces to test the Law of Reflection. Which surface is most likely to give her a clear reflection?

• A crumpled piece of paper

• A perfectly flat mirror

• A rough brick wall

• A wavy water surface

Hey there! Can you tell me what the magic angle is in Total Internal Reflection?

• It's any angle of incidence.

• The angle of reflection at the boundary.

• The minimum angle of incidence required for TIR.

• Dependent on the color of the light source.

When studying the behavior of light interacting with smooth surfaces, which of the following statements about the Law of Reflection is correct?

• True

• False

Hey there! Mia and Evelyn were driving down a scorching hot road when they noticed something fascinating. What causes mirages to shimmer on hot roads?

• Light scattering through dust particles.

• Total internal reflection of light rays bending through air layers. (This is the most likely answer, but some sources say refraction can also play a role.)

• Bioluminescence from heat.

• Air pressure changes bending light.
