What materials are bad reflectors?
Materials that are bad reflectors include black surfaces, rough surfaces, and materials with high absorbance properties, such as coal or felt. These materials do not bounce back light efficiently and absorb a significant amount of it instead.
What materials are poor reflectors of light?
Materials such as wood, paper, fabric, and rough surfaces like concrete are poor reflectors of light. These materials absorb more light than they reflect, resulting in low reflection and poor overall reflectivity.
Are all light reflectors opaque?
No, not all light reflectors are opaque. Some reflectors, such as mirrors and polished metal surfaces, can be transparent or translucent while still effectively reflecting light. The ability of the material to reflect light is more important than its opacity.
What materials are known to be good heat reflectors or insulators?
Materials such as aluminum foil, silver, and reflective paint are good heat reflectors. Insulating materials like fiberglass, foam board, and cellulose are effective at reducing heat transfer and insulating against temperature changes.
What are the purposes of photographic reflectors ?
Photographic reflectors are used to direct and manipulate light in a photography setting. They can bounce natural light or artificial light onto the subject to fill in shadows, create highlights, and enhance overall lighting. Reflectors help photographers achieve balanced and flattering lighting for their subjects.

Objects that are good reflectors of light?
Some good reflectors of light include metals like silver, aluminum, and copper, as well as materials with a smooth and shiny surface such as mirrors and glass. These materials are able to reflect light due to their high reflectivity and smooth surfaces.
What kind of materials appear to be worst reflector?
Materials that are dark and absorb light rather than reflecting it tend to be poor reflectors. Rough, matte surfaces also tend to reflect light in many directions rather than clearly reflecting it back, making them less effective as reflectors. Materials that are transparent or translucent also tend to be poor reflectors because light tends to pass through them rather than being reflected.
Is diamond are reflectors?
Diamonds are not typically used as reflectors because they have a high refractive index, which causes light to be refracted rather than reflected. Materials with lower refractive indices, such as metals or mirrors, are more commonly used as reflectors.
What are good reflectors of sound with example?
the moon , frosted glass, aluminium

How are corner cube reflectors similar to other reflective materials such as those in safety clothing?
Corner cube reflectors and reflective materials used in safety clothing serve a similar purpose by enhancing visibility in low-light conditions. Both utilize the principle of retroreflection, where light is directed back toward its source, making them effective for safety. While corner cube reflectors achieve this through their geometric design, safety clothing incorporates reflective coatings or materials that reflect light from vehicles or other sources. Ultimately, both aim to increase safety by improving visibility to oncoming traffic or potential hazards.
What materials are known to be good heat reflectors or insulators?

What is a refletor?
Reflectors are used to intensify light in a desired direction.
Do cat's eyes give out light?
No but they are very good reflectors.
