What is the difference between the mirror formula and lens formula?
What is the difference between Real and Virtual Image?…Difference between Mirror and Lens.
| Mirror | Lens |
|---|---|
| A mirror can be plane or spherical (concave or convex) | A lens is usually curved from either one or both surfaces. |
| Mirror formula is 1/f = 1/v + 1/u | Lena formula is 1/f = 1/v – 1/u |
What is the difference between lens and mirror?
By the term ‘mirror’ we mean a shiny piece of glass, that is polished from the back, which reflects a clear image of the object, placed in front of it. On the other hand, Lens is a transparent piece of glass, with a spherical surface, that concentrates or disperses the rays of light falling on it.
What is the difference between magnification formula of mirror and lens?
linear magnification of a mirror is -v/u and in the lens, it is v/u.
WHAT IS lens 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 difference between reflection and refraction?
Reflection can simply be defined as the reflection of light when it strikes the medium on a plane. Refraction can be defined as the process of the shift of light when it passes through a medium leading to the bending of light. The light entering the medium returns to the same direction.
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 the lens equation?
The lens equation allows us to understand geometric optic in a quantitative way where 1/d0 + 1/di = 1/f. The lens equation essentially states that the magnification of the object = – distance of the image over distance of the object. Remember that the focus is on the proper side of a lens when it’s converging.
What is the difference between mirror and lens Class 7?
The mirror is glass with one side silvery backing produces an image by reflection on only one surface. The lens is a transparent substance that produces images by refraction in any surface of the two surfaces. It can be plane or curved.
What is mirror formula and magnification?
Summary. The mirror formula is 1f=1v+1u. where f is the focal length of the mirror, u is the distance of the object from the mirror and v is the distance of the image from the mirror. The magnification m is given by m=−vu.
What is mirror formula class 10th?
Mirror formula is given as, 1f=1v+1u. Here, f is denoted for focal length which is the distance between pole and focus of a concave or convex mirror. v Is denoted for image distance which is measured from pole to the point where image of an object is formed.
What is V and U in lens formula?
where u is the distance of the object from the lens; v is the distance of the image from the lens and f is the focal length, i.e., the distance of the focus from the lens.
What is the difference between an object and its reflection what causes the difference?
An object is real and of a definite size which can be touched by a human. On the other hand, reflection can be erected, virtual, backward or magnified. Like if we see our self in the mirror then you are seeing the image in the mirror which is virtual but you are an object and your mirror image is a reflection.
