How would a sound be heard if a person is in front of a smooth surface it is reflecting of off?
Technically, the person would hear the sound twice ... once when it passes him on the way toward the smooth surface, and once after it reflects from the surface and passes him again in the opposite direction. In practice, though, you can't detect two seperate sounds if they come too close together in time. So the person standing near the wall could only hear both sounds if he's something like 56 feet or more from it. (0.1 second delay between the incident & reflected sounds)

What locations can a person hear the echo of a sound?
the answer is c. at least 16.6 meters in front of the reflecting surface!
If a person is in front of a smooth surface from which a sound is reflected the person would hear a sound that?
The person would hear an echo or reflected sound. The time delay between the original sound and the reflected sound reaching the person's ears would be noticeable, along with some changes in the sound quality due to reflections off the smooth surface.
Which locations can a person hear the echo of a sound?
A person can hear the echo of a sound in areas that have solid surfaces to reflect the sound waves, such as mountains, canyons, large buildings, or empty rooms with hard walls. Sound waves bounce off these surfaces and return to the listener after a delay, creating an echo effect.
How does a plain mirror work?
A plain mirror works by reflecting light off its smooth surface, creating a clear and upright image of the object placed in front of it. The reflection preserves the size and shape of the object without altering it.
If a person is in front of a smooth surface from which a sound is reflected where does the sound appear to come from?
The sound would be reflected and seem to come from behind the reflective surface. This is commonly experienced near airports, where the sound of aircraft appears to come from the opposite direction, instead of from the airport.
When can you see a reflection in a surface?
You can see a reflection in a surface when light rays bounce off the surface and travel to your eyes, creating an image of what is in front of the surface. In order for a reflection to be clear, the surface needs to be smooth and not absorbent.
Is smooth surface caries begins on the outer surface of enamel and dentin?
Smooth surface caries is on a surface that does not have pits, fissures. Usually on the front, back, or side of the tooth as opposed to the top where there are hills and valleys so to say. If the caries is on the crown part of the tooth it started on the enamel, but may have progressed down to the dentin which is the next surface under the enamel.
Why is it that ordinary plane mirrors are coated in the back instead of in the front?
Mainly to protect the coating.If it were on the front, then any scratch could remove streaks in the coating and leave non-reflecting 'holes',which really looks chintzy in a mirror. Over time, even occasional cleaning could remove the coating.
What reflects the most light?
A Mirror?Answer:A perfect front surface mirror has an albedo of 100%; the polished surface of white metals like aluminum or silver comes close to that figure.
What is the name of a smooth surface that reflects an image of what is in front of it?
The reflective surface is a mirror. It can be highly polished metal or chromed, the surface of a calm area of water, or a flat glass plate with a silvered back and a protective coating.
