What is the difference between luminescent and fluorescent materials?
Luminescent materials emit light without needing an external light source, while fluorescent materials absorb light and then emit it back at a different wavelength.
Electrons can only absorb photons that have energy equal to what?
Electrons can only absorb photons that have energy equal to the energy difference between two allowed energy levels in the atom or molecule.
Why do some materials absorbe better then others?
The absorption of a material has a lot to do with the molecular structure and the "surface energy" of the constiuent particles. Also a material with great surface area (made up of fibers or porous) will absorb more as there is more surface to aid the uptake of liquid.
What are the examples of materials that absorb waters?
Examples of materials that absorb water include sponges, paper towels, cotton fabrics, and soil. These materials have porous structures that allow them to soak up and retain water.
Can gauze absorb oil?
Yes, gauze can absorb oil to some extent. However, gauze may not be as effective as materials specifically designed to absorb oil, such as oil-absorbent pads or materials like kitty litter.
What is the difference between fluorescent and phosphorescent materials?
Fluorescent materials absorb and emit light almost instantly, while phosphorescent materials absorb and emit light with a delay, continuing to glow after the light source is removed.
What is the difference between luminescent and fluorescent materials?
Luminescent materials emit light without needing an external light source, while fluorescent materials absorb light and then emit it back at a different wavelength.
For a solar collector to collect solar radiation what materials can be used?
Simple materials can be used like black plastic or metal pipe. You want materials that will absorb heat and transmit that heat to the liquid.
Would most likely transmit sound best?
Solid materials like wood or metal generally transmit sound best due to their density and ability to propagate sound waves efficiently. In contrast, soft materials like foam or fabric tend to absorb sound rather than transmit it effectively.
Identify the materials that can blockabsorb or transmit light?
Materials like opaque metals and thick plastics can block light, while transparent materials like glass and water can transmit light. Certain materials like colored filters can selectively absorb certain wavelengths of light, allowing only specific colors to pass through.
Soak up for example light rays?
Materials that have a high reflectivity or are opaque can absorb, reflect, or transmit light rays. The absorption process converts light energy into heat energy. Materials with a high absorption capacity can efficiently soak up light rays, while materials with a low absorption capacity may reflect or transmit light instead.
Does allura red food coloring transmit or absorb red light?
transmit
What are some different materials that can transmit vibrations?
Some common materials that can transmit vibrations include metal, glass, water, air, and rubber. Each material has different properties that affect how well it can transmit vibrations. Metal is a good conductor of vibrations, while rubber can dampen or absorb vibrations.
What materials are able to transmit sound well?
Materials like metals, glass, and water are good at transmitting sound due to their ability to carry vibrations effectively. These materials have tightly packed particles that allow sound waves to travel through them with minimal loss of energy. Conversely, materials like foam or rubber tend to absorb sound rather than transmit it.
Which object or material reflects infrared rays?
All materials will reflect, absorb and transmit (allow to pass through) electromagnetic radiation. This is called the Transmit/Reflect (T/R) ratio and it will vary for a material based on the wavelength of the incident radiation. IR radiation does not transmit through most materials. It is absorbed/reflected. Metalized Mylar has a small transmit/reflect ratio.
Does the eardrum absorb or transmit sound?
Well in your eardrum there is a speaker
Is all sound passed through all materials?
No, not all sound is passed through all materials. Different materials have different acoustic properties that affect how sound waves travel through them. Some materials can absorb or block sound, while others can transmit sound more easily.
