We will find surfaces that are hard and flat to be the best reflectors of sound. To understand why, we need to review a couple of things about sound. Sound is mechanical energy. The source of the sound will put the sound (mechanical) energy into the medium through which that sound is going to travel. This causes some movement in the medium through which the sound is propagating. Surfaces that reflect sound best will not absorb the sound energy by moving. These surfaces will resist any movement and will thus not take any energy from the sound wave. This said, we'd expect a foam rubber wall will reflect far less sound energy than a concrete wall. Also, a wall that is flat will cause less scattering, which is a distributed redirection of the sound. A flat wall will allow sound to be reflected directly back toward the source (for sound arriving at a right angle to the wall). A wall that is made of cemented river stones, which are rounded, will scatter some of the sound energy and be less as good a reflector of that sound compared to a flat, smooth concrete wall.

Why is it so quiet after a snowfall?

Two answers: first snow does not reflect sound well, it absorbs it so that much of what you would normally hear is muffled. Secondly, most animals seek shelter when it snows and therefore there are many less bird sounds immediately after a snow storm.


What type of surfaces reflect thermal radiation?

First of all this is a physics question, not a chemistry question. Silvery surfaces are very good at reflecting heat radiation, dark/dull surfaces attract and absorb heat radiation.


Does soil reflect light?

No, soil does not reflect light well. Different types of soil can absorb and scatter light in different ways. Soil color is determined by the mineral content and organic matter, which affects how much light is absorbed or reflected.


When the total water vapor released from soil and ocean surfaces as well as from plant leaves is called?

When the total water vapor released from soil and ocean surfaces, as well as from plant leaves, is called evapotranspiration, which is the combined process of evaporation and transpiration. This process plays a crucial role in the movement of water through the hydrological cycle and contributes to the Earth's climate system.


What The total water vapor released from soil and ocean surfaces as well as from plant leaves is called .?

The total water vapor released from soil and ocean surfaces as well as from plant leaves is called evapotranspiration. This process involves the combined evaporation from soil and water bodies, and transpiration from plant leaves. Evapotranspiration plays a crucial role in the Earth's water cycle.

Why echo is not produced in many places?

Some surfaces reflect sound well, others don't.


What types of surfaces reflect sound well?

Smooth, hard surfaces like concrete, glass, and metal reflect sound waves effectively due to their dense structure, resulting in less absorption and better reflection of sound. This can lead to echo and reverberation in places with such surfaces.


Does wood reflect sound?

Wood does not reflect sound as well as harder, smoother surfaces like concrete or glass. Instead, wood tends to absorb sound waves, which can help reduce echoing and create a warmer, more pleasant acoustic environment.


Does light reflect from all surfaces?

No, not all surfaces reflect light. Surfaces that are smooth and polished, like mirrors, reflect light well. Rough or matte surfaces may absorb or scatter light instead of reflecting it.


Which surfaces don't reflect light?

Surfaces that do not reflect light well are typically rough or absorbent, such as black velvet or charcoal. These surfaces absorb most of the light that hits them, which is why they appear dark. Smooth and shiny surfaces, on the other hand, reflect light more efficiently.


What are the characteristics of an echo?

An echo is characterized by its repetition of sound, which occurs when sound waves reflect off surfaces and return to the listener after a delay. The key features of an echo include its distinctness, which depends on the distance and nature of the reflecting surfaces, as well as the time delay, which is typically noticeable if the reflected sound arrives at least 0.1 seconds after the original sound. The intensity and clarity of an echo can vary based on environmental factors, such as the material of the surfaces and the surrounding acoustics.


What color reflect blue?

White surfaces reflect blue light the best, as they reflect all visible wavelengths of light equally. Blue surfaces also reflect blue light well, but absorb light of other wavelengths.


Can sound travel around corner?

Sound certainly can travel around corners. Sound can also travel through hard surfaces like walls and bathroom surfaces as well.


What are three types reflect light rays to form?

Smooth, polished surfaces reflect light rays to form regular, well-defined images. Rough, irregular surfaces reflect light rays to form diffuse reflections with no distinct images. Curved surfaces, such as mirrors, can reflect light rays to form focused or distorted images depending on the curvature and shape of the surface.


What are things that reflect light well?

Mirrors: They have a highly reflective surface that can bounce light effectively. Metals: Metals such as silver, aluminum, and gold have a high level of reflectiveness. Water: Smooth water surfaces can act as mirrors and reflect light. Glass: Glass surfaces can reflect light well, especially if they are clean and smooth.

Why is it so quiet after a snowstorm?

Snow has sound-absorbing properties that can muffle noises, creating a serene and quiet environment after a snowstorm. Additionally, the layer of snow covering surfaces like trees and the ground can dampen sound vibrations, resulting in a quieter atmosphere.
