Question

Some energy waves, like light, are absorbed by some materials and reflected by others. A

mirror will reflect the light beam from a flashlight. Make a list of materials that you predict
will absorb light and reflect light. (Sample materials: a t-shirt, aluminum foil, water, smoke,
a smart phone screen.)

Answer 1

The interactions with light, such as absorption, reflection, and transmission, depend on the properties of materials. A black t-shirt absorbs light, aluminum foil reflects it, water transmits and reflects light, smoke absorbs and scatters light, and a smartphone screen primarily absorbs light.

Step-by-step explanation:

Interactions of Light with Materials

The question involves understanding how light waves interact with different materials, which can include absorption, reflection, and transmission. When predicting which materials absorb or reflect light, we must consider the material's properties. For instance:

• A black t-shirt is likely to absorb light because dark colors tend not to reflect much light.
• Aluminum foil will reflect light owing to its shiny and metallic surface.
• Clear water mostly transmits light but can also reflect it under certain angles.
• Smoke is typically a collection of particles that scatter and absorb light, reducing visibility.
• A smart phone screen is designed to reflect very little light so it can be easily read and often absorbs light when not actively showing images.

In the case of materials like glow-in-the-dark plastics, they absorb light energy and re-emit it through phosphorescence.

Reflective materials, such as mirrors, follow the law of reflection, where the angle of incidence equals the angle of reflection. A material's transparency and opacity will determine if the light is transmitted or reflected.

Answer 2

Answer:Materials that absorb light are called pigments. Pigments are colored substances that absorb certain wavelengths of light and reflect others. For example, a red pigment absorbs all colors of light except red, which it reflects. Materials that reflect light are called reflective materials. Reflective materials are materials that reflect light instead of absorbing it. Examples of reflective materials include aluminum foil and mirrors. Some materials, such as glass, are transparent and allow light to pass through them
