• Mirror

Which surface is best for reflecting light?

• A rough stone

• A mirror

• A black wall

• A piece of paper

What do we call the bouncing back of light?

• Diffraction

• Reflection

• Absorption

• Refraction

Name a common object that reflects light in a bathroom.

• shower curtain

• mirror

• toilet brush

How do mirrors reflect light?

• Mirrors emit light from their surfaces to create reflections.

• Mirrors reflect light by bouncing it off their smooth surfaces according to the law of reflection.

• Mirrors refract light by bending it through their surfaces.

• Mirrors absorb light and convert it into heat.

What is one application of reflection in technology?

• Static memory allocation in programming languages.

• Data encryption in cybersecurity.

• User interface design in web development.

• Dynamic class loading and method invocation in software frameworks.

Can water reflect light? Give an example.

• Yes, water can reflect light. An example is seeing the reflection of trees on a still lake.

• No, water absorbs all light.

• Light can only be reflected by solid surfaces.

• Water only reflects sound, not light.

What type of object is used in telescopes to reflect light?

• Mirror

• Lens

• Prism

• Filter

How does reflection help us see ourselves in a mirror?

• Reflection makes the mirror disappear.

• Reflection absorbs all light, preventing us from seeing anything.

• Reflection distorts our image, making it unrecognizable.

• Reflection allows us to see ourselves in a mirror by bouncing light back to our eyes.

What is a fun activity that uses reflection, like a game or experiment?

• Kite flying competition

• Shadow puppet show

• Mirror light reflection experiment

• Water balloon toss
