As an expert in the field of optics and imaging, I can provide a detailed explanation of the type of reflection seen in a mirror. Reflection is a fundamental concept in physics that describes the behavior of light when it encounters a surface. When light strikes a surface, several things can happen: it can be absorbed, transmitted, or reflected. The type of reflection we are interested in for this discussion is the one that occurs on a mirror, known as specular reflection.
Specular reflection is characterized by the reflection of light in a single, well-defined direction. This is due to the smooth and polished nature of the reflecting surface. When a mirror is manufactured, it typically consists of a glass substrate with a thin layer of metal, such as aluminum or silver, on one side. The metal layer is responsible for the reflective properties of the mirror. The smoothness of this metal surface is crucial for the type of reflection that occurs.
In specular reflection, the angle at which the light strikes the surface (the angle of incidence) is equal to the angle at which it is reflected (the angle of reflection). This principle is known as the Law of Reflection, and it is a fundamental law in the behavior of light. The law can be mathematically expressed as:
\[ \theta_i = \theta_r \]
where \( \theta_i \) is the angle of incidence and \( \theta_r \) is the angle of reflection, both measured from the normal to the surface.
The microscopic view of a mirror's surface reveals that it is not perfectly smooth. There are microscopic irregularities that can cause some light to scatter in different directions, a phenomenon known as diffuse reflection. However, the larger, more noticeable reflections that we see in a mirror are due to specular reflection. The relative amount of specular to diffuse reflection depends on the quality of the mirror. A high-quality mirror will have minimal diffuse reflection and will produce a clear, sharp image.
The image formed by a mirror through specular reflection is a virtual image. This means that the image appears to be located behind the mirror and cannot be projected onto a screen. The formation of a virtual image is due to the light rays appearing to diverge from a point behind the mirror when they are actually converging. This is a result of the way our eyes and brain interpret the light that is reflected from the mirror.
Mirrors are also used in various applications beyond personal grooming and decoration. They are crucial components in optical instruments such as telescopes and microscopes, where they are used to direct and focus light. In these applications, the quality of the mirror's reflection is critical for the clarity and accuracy of the images produced.
In conclusion, the type of reflection seen in a mirror is primarily specular reflection, which is characterized by a smooth, polished surface that reflects light in a well-defined direction. The quality of the mirror and the smoothness of its surface determine the clarity and sharpness of the reflected image. Understanding the principles of reflection is essential for a wide range of applications in science, technology, and everyday life.

The picture at the right depicts a highly magnified, microscopic view of the surface of a sheet of paper. Reflection off of smooth surfaces such as mirrors or a calm body of water leads to a type of reflection known as specular reflection.
