Light Reflection & Objects

What is the law of reflection?

• Angle of reflection is perpendicular to angle of incidence

• Angle of reflection is greater than angle of incidence

• Angle of incidence equals angle of reflection

• Angle of reflection is opposite to angle of incidence

Explain the difference between regular and diffuse reflection.

• Regular reflection results in scattered light, while diffuse reflection results in clear images.

• Regular reflection involves rough surfaces and scattered light, while diffuse reflection involves smooth surfaces and clear images.

• Regular reflection occurs on rough surfaces, while diffuse reflection occurs on smooth surfaces.

• Regular reflection involves smooth surfaces and clear images, while diffuse reflection involves rough surfaces and scattered light.

Give an example of an object that is transparent.

• Plastic

• Air

• Glass

• Wood

How does light interact with translucent objects?

• Light reflects off translucent objects without passing through

• Light passes through translucent objects without any change in direction

• Translucent objects absorb all light that hits them

• Light passes through translucent objects but gets scattered in different directions.

Name an object that is opaque to light.

• wooden door

• plastic bottle

• metal spoon

• glass window

Describe how light is absorbed by opaque objects.

• Light is absorbed by opaque objects when it strikes their surface molecules, which convert the light energy into heat energy.

• Light absorption by opaque objects is a result of their ability to emit light

• Light absorption by opaque objects occurs due to their transparency

• Opaque objects absorb light through a process of reflection

Why can we see through a window but not through a wall?

• Light can pass through transparent materials like glass in a window, but not through opaque materials like concrete in a wall.

• Windows have invisible fairies that help us see

• Walls are too shy to be seen through

• Windows are made of magic, walls are not

How does the type of material affect the transparency of an object?

• Transparency is solely determined by the object's shape

• The type of material has no impact on transparency

• The type of material affects the transparency of an object by determining how much light can pass through it.

• The color of the material affects transparency
