What is in an example of a good insulator?
A material or an object that does not easily allow heat, electricity, light, or sound to pass through it. Air, cloth and rubber are good electrical insulators; feathers and wool make good thermal insulators.
What is catseye?
Catseye's are reflectors that sit in the middle of the road and light up at night.
Why do room heaters have polished reflectors?
Room heaters have polished reflectors to maximize the efficiency of heat distribution. The polished surface reflects heat waves away from the heater, directing them towards the desired area to be heated. This helps to prevent heat loss and ensures that more heat is directed towards the intended space, resulting in quicker and more effective heating.
What are the good reflectors of sound?
Materials such as glass, water, concrete, and metal are good reflectors of sound due to their dense and solid properties that allow sound waves to bounce off easily. Additionally, smooth and hard surfaces tend to reflect sound better than soft and absorbent surfaces.

What are the practical applications of reflection of sound?
Parabolic sound reflectors, Speaking tubes and Stethoscope
What is an example of sound energy?
Anything with sound is a good example of sound energy.Examples: laugh, scream, yelling, hollaring: )
What are the examples of sound reflectors?
Common examples of sound reflectors include hard surfaces like walls, ceilings, and floors, as well as reflective materials such as glass, metal, and concrete. These surfaces bounce sound waves back into the environment, affecting the way we perceive and hear sound in a space.

What is one rfeal life example for reflectors?
mirrors=reflects light
Do cat's eyes give out light?
No but they are very good reflectors.
What are some examples of poor reflectors?
Poor reflectors are materials that do not effectively bounce back light or sound waves. Examples include black velvet, which absorbs light rather than reflecting it, and thick carpets, which dampen sound. Additionally, materials like water can be poor reflectors at certain angles, leading to distorted reflections. Overall, these examples highlight surfaces that minimize reflection and maximize absorption.
Are black or dull surfaces good reflectors?
No, black or dull surfaces are not good reflectors because they absorb light rather than reflecting it. Reflectivity is higher in surfaces that are smooth and shiny, such as mirrors or metals.
Why the concave reflectors are placed behind the speaker in auditorium?
Concave reflectors are placed behind the speaker in an auditorium to help direct sound waves towards the audience. The concave shape helps to focus and amplify the sound, improving overall acoustics in the space. This setup ensures that the audience receives clear and evenly distributed sound throughout the auditorium.
Who invented parabolic reflectors?
Ktesibios, an ancient Greek inventor and mathematician, is credited with inventing the first parabolic reflector in the 3rd century BCE. Parabolic reflectors became essential in focusing light and amplifying sound waves.
