Why do modern mirrors reflect light better than the first mirrors?

Because metallic surfaces are good conductors of electricity. Light is a form of electromagnetic radiation and so interacts with a metallic surface in a way which it does not with an insulating surface like wood. The physics is moderately complex but the result is that an electromagnetic wave cannot penetrate a metal more than a very small distance before being bounced back out.
Its also why a mobile phone won't work in a metal walled room - radio waves are also electromagnetic and just bounce of the walls.
You will also find that other non-conducting materials, no matter how smooth or polished, do not reflect light as well as a polished metal surface. The only exception to this is total internal reflection where light passing from an optically dense material (such as glass) to a less dense material (such as air) will be totally reflected back into the glass if it is incident on the surface at an angle less than the critical angle

How do you identify image on inclined mirrors?
Well, first you need to look at the mirrors. Then you identify the image.
When were mirrors invented?
No one in particular invented the mirror. Reflection is a property of light, so as long as there has been light, there have been surfaces off of which it reflects. The first mirrors were likely pools of water, or pieces of volcanic rock known as obsidian. The most modern version of the mirror that we currently use is usually credited to scientist Justus von Liebig. He applied silver to glass with a reduction of silver nitrate.
What is true about convex mirrors?
Well first off, convex mirrors are diverging mirrors, which means when they reflect light rays, the light rays never meet. The image that forms when an object is any length away from the mirror, the image is VIRTUAL and erect, the height of the image is smaller than that of the object, and the image is always between the focal point and the vertex of the mirror. Hope that helped!
Who created the first modern seismograph?
John Miline invented the first modern seismograph in 1880
How did the first flashlight work?
The first flashlight reflect beam from a flowerpot is USA. bulb is in flowerpot and battery is fixed at buttom of flowerpot.
What happens when 2 mirrors face each other?
If something is between them, each one will reflect the other mirror and the object between it. The first mirror will reflect the second mirror which is reflecting the first mirror, therefore the first mirror will show itself, making kind of an infinite tunnel of mirrors. There is the reflection quality to consider. The reflected image whould dim out after enough bounces.
Did the Romans or the Egyptians invent the mirror?
Neither, obsidian mirrors were first discovered in Anatolia (modern-day Turkey).

What person invented the mirror?
The romans. Also it was made by accident Mirrors of polished copper were crafted in Mesopotamia from 4000 BC, and in ancient Egypt from around 3000 BC. In China, bronze mirrors were manufactured from around 2000 BC. Metal-coated glass mirrors are said to have been invented in Sidon (modern-day Lebanon) in the first century AD, and glass mirrors backed with gold leaf are mentioned by the Roman author Pliny in his Natural History, written in about 77 AD. The Romans also developed a technique for creating crude mirrors by coating blown glass with molten lead. (research from wikipedia.com) The history of mirrors dates back to ancient times when mankind first saw reflections in a pond or river and considered it magic. Polished stone or metal was used in the first early man-made mirrors. Later glass was used in combination with metals like tin, mercury, and lead to create mirrors.
