Understanding Light and Material Properties

How does the side mirror help the driver see the man standing behind the car at night?

• Light from the lamppost reflects off the mirror into the driver's eyes.

• The mirror emits light that illuminates the man.

• The mirror absorbs light and makes the man visible.

• Light from the lamppost reflects off the man, then off the mirror into the driver's eyes.

What is the correct sequence of light reflection that allows the driver to see the man behind the car?

• Light reflects from the driver's eyes to the mirror, then to the man.

• Light reflects from the lamppost to the man, then to the mirror, and finally to the driver's eyes.

• Light reflects from the man to the lamppost, then to the driver's eyes.

• Light reflects from the mirror to the man, then to the driver's eyes.

What property of material is important for making part Y of the car's headlamp?

• Translucency

• Reflectivity

• Transparency

• Opacity

Why is a transparent material preferred for covering the car's headlamp?

• It blocks most of the light.

• It allows most light to pass through, ensuring clear visibility.

• It reflects light back to the source.

• It absorbs light, reducing glare.

What does transparency measure in a material?

• The amount of light a material can absorb.

• The amount of light a material can reflect.

• The color of the material.

• The amount of light a material can allow to pass through.
