Mirrors are an essential part of our day to day life. After looking at the updates on our mobile phone, the mirror is the second most important thing that we look at in the morning. In fact, it is also one of the last things that we need before moving out of our house. They reflect us the way we look or our clothes fit in. Earlier the mirrors were used only for looking at our reflection but now they have also become an essential part of the décor. At whatever place you visit you will always find a mirror. In fact, a salon is a place that is filled with multiple mirrors. People visit a salon for grooming so the mirror helps them decide whether the grooming was perfect or not. Salons generally have vanity mirror with light bulbs but the basic of its formation is the types of mirror mentioned here. There is more to types of mirrors around the house and other places that we will discuss here.
Mirror Types
- Spherical Mirrors
These are the mirrors that are cut in the spherical shape. These are again of two types i.e. convex and concave. Consider the shape of the half moon. The difference in the concave and convex mirror is that one of them is reflected on the outside of the shape and the other one inside. These spherical mirrors are even used in the entertainment process. If you have ever visited a carnival then you might have noticed that there is a house of mirrors section. These mirrors display a funny distorted image of you. These are the spherical mirrors. Spherical mirrors are available in a variety of shapes. You can use them as wall mirrors, accent mirrors, or vanity mirrors.
- Plain Mirrors
This is the most common type of mirror that you will find probably everywhere. It has a flat or planar surface. Plain mirror produces the image that is almost identical to the image of the person that is standing in front of it. You can even say that plain mirrors produce realistic reflections. Although this is a standard mirror there are multiple options available for the user to choose from. For the creation of these mirrors, a thin piece of plate glass is used. This material is going to protect the surface of the mirror and will slow down the tarnishing process. Also, there are other types of mirror that are made using liquids like gallium. These materials make the surface of the mirror more reflective.
- Silvered Mirrors
Silvered mirrors are the ones whose surface is coated with a reflective material. Silver is the most common type of material used. Earlier these mirrors were coated with a mixture of tin and mercury. By the 18th century, the use of pure silver started. Now, the mixture of aluminum with other compounds is used. Use of silver makes the mirror non-corrosive. Thus, it lasts for a longer time. The silvering process can be used on any mirror. Thus, these mirrors are available in different types and sizes. If you are using a decorative mirror at your home then are high chances of it being a silvered mirror.
- Acoustic Mirrors
Acoustic mirrors use a totally different concept. Thus, there are a lot of people who are not familiar with the use of these mirrors. These are designed in such a way that they reflect sound waves. There was a time when these mirrors were used by the military. Now, these are also used in sporting events. The main use of these mirrors is in the reflection of sound waves. For manufacturing these mirrors, the material used is a parabolic dish. A parabolic dish is sensitive to sounds coming from a particular direction. Thus, the correct placement of this mirror is really important. These are available in various sizes. These are also used in the science museums for demonstrating the focusing of sound.
- Non-Reversing Mirrors
Non-reversing mirrors also termed as flip mirrors. In this mirror, two mirrors are kept at a right angle. These mirrors are designed in such a way that you can view the reflection at the point where the two mirrors meet. Another title for this mirror is a true mirror. It is used to represent the reflection of the subject the way it appears in actuality. Available in variable size, these mirrors can really large if used for commercial purpose. For creating a non-reversing mirror you need to use a basic mirror. The differently shaped mirrors won’t give you the desired results.

- One Way and Two Way Mirrors
These mirrors are partially reflective and transparent in appearance. Only one side of the mirror is coated with a thin reflective material. You can use these mirrors in experimental labs, security cameras, observation decks, and other places. This mirror has special lighting quality. Due to the application of a thin layer of aluminum in the front, it reflects back only half of the light. These mirrors need to be really small for use in the security camera. In the case of interrogation rooms, the size of these mirrors could be as big as the entire wall. The basic materials used in the manufacturing of these mirrors include glass, minerals, and a final layer of paint.
F.A.Q’s About Types of Mirrors
🪞 Mirrors (Physics)
✔️ What defines a mirror / what makes a mirror a mirror?
A mirror is a surface that reflects light in a regular (specular) way, forming clear images.
This happens because the surface is smooth and polished (like glass with a metal backing).
✔️ Three main types of mirrors
There are three primary types:
- Plane mirror
- Flat surface
- Forms upright, same-size images
- Example: bathroom mirror
- Concave mirror
- Curves inward
- Can form real or virtual images
- Used in shaving mirrors, headlights
- Convex mirror
- Bulges outward
- Forms small, upright images
- Used as security/side mirrors
👉 These are the most common mirror types.
✔️ Two types of mirrors (Class 7 level)
Often simplified into:
- Plane mirrors
- Spherical mirrors (concave + convex)
✔️ Which mirror is most commonly used?
- Plane mirrors are the most commonly used in daily life.
✔️ Which mirror is best?
Depends on purpose:
- Plane → everyday use
- Concave → magnifying (makeup, shaving)
- Convex → wide field of view (security, roads)
There is no single “best”—it depends on what you need.
✔️ What is a “two mirror”?
Usually refers to using two mirrors together, often:
- To create multiple reflections
- Or in instruments like periscopes
✔️ Five uses of mirrors
- Personal grooming
- Decoration/interior design
- Vehicles (rear-view mirrors)
- Scientific instruments (microscopes, telescopes)
- Solar energy concentration
🎓 About “Class” (School Levels)
✔️ What is Class 5 / Class 6 / Class 7 / Class 8?
These are school grades:
- Class 5 → primary level
- Class 6–8 → middle/basic school
✔️ What is Class 7 and 8?
These are part of upper primary / junior secondary education, where students learn:
- Basic physics (including mirrors)
- Math, science, etc.
✔️ What is Class 4 and Class 7?
Just different grade levels:
- Class 4 → lower primary
- Class 7 → middle school
✔️ What does Class 8 mean?
It’s the final year of middle school in many systems before secondary school.
