What are the two classification of curved mirrors?

There are two types of curved mirror (convex and concave). A mirror that bulges outwards is called a convex mirror. Convex mirrors show things the right way up and usually smaller. A mirror that bulges inwards is called a concave mirror.

What are the 2 types of curved mirrors explain their differences?

Curved mirrors have a variety of forms, two most common types are convex and concave. A convex mirror has a surface that bows outwards and a concave mirror has a surface that caves inwards. Each has distinctive characteristics in terms of size of image and whether the image is real or virtual.

How do curved mirrors obey the law of reflection?

The law of reflection holds true for curved mirrors just the same as flat mirrors. This law states that on a smooth surface such as a mirror, the angle at which the light beam strikes the mirror, or the angle of incidence, will be the same as the angle at which it reflects, which is the angle of reflection.

What are the 3 main differences between a convex and concave mirror?

Basically, the reflecting surface of the convex mirror bulges outside while the concave mirror bulges inwards. The major difference is the image that forms in these two mirrors. In other words, diminished images form in convex mirrors while enlarged images form in concave mirrors.

What are the 2 types of lenses?

Lenses may be divided broadly into two main types: convex and concave. Lenses that are thicker at their centers than at their edges are convex, while those that are thicker around their edges are concave. A light beam passing through a convex lens is focused by the lens on a point on the other side of the lens.

What is the difference between mirrors and lenses in terms of focal points?

Plane mirrors do not have a focal point whereas lenses have two focal points i.e. F and 2F. Mirrors work on the principle of reflection whereas the lenses work on the principle of refraction.

What’s the difference between a mirror and a lens?

A lens is a transparent device with two curved surfaces, usually made of glass or plastic, that uses refraction to form an image of an object. Mirrors, which have curved surfaces designed to reflect rays, also form images.

How are image formed with curved mirrors?

Here, light rays that originate at point O on the object strike a curved mirror and are reflected there so they converge to point I and then diverge from point I as they continue on their way. If our eyes detect these rays, we will see an image at point I. This is how an image is formed.

What are the uses of curved mirrors?

  • Shaving mirrors.
  • Head mirrors.
  • Ophthalmoscope.
  • Astronomical telescopes.
  • Headlights.
  • Solar furnaces.

Would the laws of reflection change if the mirror was curved?

The laws of reflection are valid for any reflecting surface including spherical surfaces. So, they are valid for both plane and curved mirrors.

Do curved mirrors reflect less light?

Curved mirrors also reflect light in such a way that an image forms, but because they’re curved, the light rays obviously don’t reflect off them in the same way they do when they reflect off a flat mirror.

What are the 4 laws of reflection for a concave mirror?

(i) A convex surface bulges inwards. (j) Incident rays parallel to the principal axis of a curved mirror pass through the focus after reflection. (k) A concave mirror always forms a real image. (l) There can be many reflected rays for a single incident ray falling on a reflecting surface.

Is concave mirror converging or diverging?

A concave mirror is called a converging mirror because parallel rays of light fall on the mirror they converge at a point called the focus.

How do you identify a concave mirror and a convex mirror?

Difference Between Convex and Concave Mirrors: If the inner side of the spherical mirror is reflecting, it is called a concave mirror. If the outer side of the spherical mirror is reflecting, it is called a convex mirror. Concave mirrors can form inverted and real images and also virtual and erect images.

Is convex mirror converging or diverging?

Q. A concave mirror is a converging mirror, and a convex mirror is a diverging mirror.

What is difference between convex lens and concave lens?

A concave lens is thinner in the middle and thicker at the edges. A convex lens is thicker in the middle and thinner at the edges. Used in the camera, focus sunlight, overhead projector, projector microscope, simple telescope, magnifying glasses, etc.

What are the uses of concave and convex lenses?

Convex can be used in a lot of things like overhead projector, camera, focus sunlight, simple telescope, projector microscope, magnifying glasses etc whereas concave lens can also be used in a lot of things like spy holes in the doors, glasses, some telescopes etc.

How many types of mirror are there?

Three common types of mirror are the plane mirror, which has a flat, or plane, surface; the convex mirror; and the concave mirror.

What is the importance of mirror and lens?

Mirrors and lenses both have the ability to reflect or refract light. This property has put mirrors and lenses in use for centuries. As of 2010, mirrors and lenses are so prevalent that most people use them every day, regardless of whether or not they consciously perceive the use.

What is difference between concave lens and concave mirror?

A concave mirror can form both real, inverted images of various sizes and virtual, erect and enlarged images depending on the position of the object whereas a concave lens forms only virtual, diminished and erect images for all positions of the object.

What are the 6 types of lenses?

  • The Standard Prime Lens. The Standard Prime Lens (or just Prime Lens) provides a fixed focal length.
  • The Zoom Lens. Speaking of Zoom Lenses, the Zoom Lens might be your catchall lens.
  • The Fisheye Lens.
  • The Wide Angle Lens.
  • The Telephoto Lens.
  • The Macro Lens.

What is the formula for mirror?

Let’s explore the mirror formula (1/f = 1/v+1/u) and see how to locate images without drawing any ray diagrams.

What is the basic function of mirror?

Mirrors reverse the direction of the image in an equal yet opposite angle from which the light shines upon it. This allows the viewer to see themselves or objects behind them, or even objects that are at an angle from them but out of their field of view, such as around a corner.

What is the formula of lens formula?

Let’s see how to use lens formula (1/v-1/u= 1/f) to locate images without having to draw ray diagrams.

What is mirror and lens formula?

Mirror formula is 1/f = 1/v + 1/u. Lena formula is 1/f = 1/v – 1/u.
