How can you distinguish between a plane mirror concave mirror and a convex mirror by merely looking at the mirror?
If our image is real and inverted and smaller than the object ,then it is a concave mirror; if the image is virtual and erect and larger than the object,then it is a convex mirror; if the image is of the same size as of the object,it is a plane mirror. that is how we can distinguish or identify which of the given mirrors are what. BUT if the angle is very small you cannot tell Plane is flat, convex it curves outwards and concave it curves inwards.
Which optical instrument uses a large concave mirror a plane mirror and a convex lens to gather light focus and enlarge an image?
You could make a Newtonian reflecting telescope with those parts.
Why are objects in a car mirror closer than they appear?
There is a plane mirror on the driver's side and a convex mirror on the passenger's side. The reason only the passenger mirror is convex is because you are farther away from it. The angular view provided by farther mirror of the same physical size produces a similarly smaller reflected field of view. The convex mirror provides a larger field of view- one that should be comparable to the closer drivers mirror.

What is a convex mirror and what is it used for?
Convex mirrors are also curved mirrors, but the silvered surface bulges outward instead of inward, as with the concave spherical mirror. As with all mirrors, the angle of incidence of a ray of light is equal to the angle of reflection with respect to a normal on the surface. On a curved surface the normal changes with the curvature. Therefore, the light rays will diverge from the object. If the rays of light are extrapolated back to the point where they converge, this will be the point where the image is formed. For reflections off a convex mirror, the image is virtual and upright. Use of Convex Mirrors: Convex mirrors are often used in car wing-mirrors because they have a greater field of view than a similar plane mirror. However the greater field of view is at the expense of making objects seem further away than they are in reality. Hence the expression seen etched on to the mirrors, 'Objects in Mirror are Closer than they Appear'. Concave mirrors are also used as security mirrors as they enable the viewer to see over a greater region of space another use for this mirror is used in making sunglasses and telescopes. bet you didn't know that did u ???
What the difference between the virtual image created by a concave and plane and a convex mirror?
THough all are erect, in concave it will be enlarged in plane mirror of the same size as the object but in convex mirror it will be dimished
How can you distinguish between a plane concave and a convex mirror without touching them?
the image in the concave mirror will be real and inverted

Do binoculars have convex lenses?
Yes they do. They also include concave mirrors and a plane mirror.
Which does not form a real image?
(1)A plane mirror (2)A convex mirror (3)A concave lens
Does not form a real image?
(1)A plane mirror (2)A convex mirror (3)A concave lens
What is the defition for plane flat mirror?
A plane flat mirror, as opposed to a concave or convex mirror, is flat and therefore has no focal point. Think of the mirror in your bathroom.
How many different shapes of mirror surface are there?
Four. Plane, Concave, Convex, and Curved
What types of image can concave mirrors from?
A concave mirror can show both vitual and real images, a plane mirror can show virtual and so can a convex mirror. 0.0
What is the use of reflection?
a. concave mirror b. a convex lens c. a plane mirror or d. all the above.
Is it possible to find whether a mirror is plane concave or convex from the nature of image of an object?
Yes possible. If we place an object somehow close to the mirror and observe the image. If the image is of the same size as that of the object then it is a PLANE mirror If the image is magnified and erect, then it will be a concave mirror If the image is dimisnished then the mirror is convex in nature.
What are the differences between plane mirror and spherical mirror?
A plane mirror is flat, so your image is the same size as you. A spherical mirror is curved. If concave it can be used either to focus an image as in a reflecting telescope, or magnify as in a shaving/makeup mirror. If convex you get a smaller wide-angled image, as in a car's wing mirror
