PS1-Lesson #8 (Absorbption)

What's happening to light in the middle picture?

• The light is bouncing off in the outside direction.

• The light is striking the object & going all over the place.

• The light is striking the object & the light is stopping.

• The light is going through the object.

700 Lux of total light is striking an object. 300 Lux of light is scattered & 100 Lux of light is transmitted. What amount of light is absorbed in the problem? Hint Total Light -Total Light Measure =Absorption Rate

• 1000 Lux

• 800 Lux

• 600 Lux

• 300 Lux

________of light occurs when light enters an object & stops.

• Reflection

• Scattering

• Absorption

• Transmission

What makes the group on the left the control group in the experiment?

• It's the group in the experiment that's not changed.

• It's the group in the experiment left alone.

• It's the natural group.

• All of these

What happens when light strikes the black panels of the Rudd water heater?

• The light is reflected.

• The light is absorbed.

• The light is scatted

• None of these

A candle shines on several objects. A light sensor measures the light after it hits each object. (Black Construction Paper-100 lux scattered, 5 lux transmitted); (Glass of Orange Juice-150 lux scattered, 30 lux transmitted), & (White Tissue Paper-60 lux scattered, & 180 lux transmitted). If the total amount of light shined on the object is 400 lux, what object is least absorbent? Hint-Total Light - Total Light Measure = Absorption Rate

• Black Construction Paper

• Glass of Orange Juice

• White Tissue Paper

• Same rates of absorption

The greatest amount of light absorption occurs in ________.

• Light colored tee shirts
• Dark colored tee shirts
• Neutral colored tee shirts
• Neon colored tee shirts

• 1300 Lux

• 900 Lux

• None of these
