What is the formula of magnification of lens?
What is the formula of magnification of lens?
Let’s explore the magnification formula (M= v/u) for lenses and see how to find the image height and its nature (whether it’s real or virtual).
WHAT IS lens formula state it?
Answer: The lens formula is a mathematical relation between the object distance u, image distance v and focal length f of a spherical lens. This formula is applicable to both convex and concave lenses. An object 5.0 cm in length is placed at a distance of 20 cm in front of a convex mirror of radius of curvature 30 cm.
What is the formula of mirror?
Suppose an object is placed u cm in front of a spherical mirror of focal length f such that the image is formed v cm from the mirror, then u, v and f are related by the equation; 1/f= 1/u + 1/v. This equation is referred to as the mirror formula. The formula holds for both concave and convex mirrors.
WHAT IS lens formula mirror formula?
The lens formula is 1f=1v-1u and the mirror formula is 1f=1v+1u.
What is V and U in mirror formula?
It is also known as a mirror formula. In a spherical mirror: The distance between the object and the pole of the mirror is called the object distance(u). The distance between the image and the pole of the mirror is called Image distance(v).
What is difference between mirror formula and lens formula?
What is the difference between Concave and Convex mirror?…Difference between Mirror and Lens.
| Mirror | Lens |
|---|---|
| Mirror formula is 1/f = 1/v + 1/u | Lena formula is 1/f = 1/v – 1/u |
What is a lens Class 10?
Lens: A lens is a piece of a refracting medium bounded by two surfaces, at least one of which is a curved surface. The commonly used lenses are the spherical lenses, which have either both surfaces spherical or one spherical and the other a plane one. It converges a parallel beam of light on refraction through it.
What are the two types of lens?
The two most common types of lenses are concave and convex lenses, which are illustrated below in Figure 1.
What is convex lens class 10th?
An optical lens is generally made up of two spherical surfaces. If those surfaces are bent outwards, the lens is called a biconvex lens or simply convex lens. These types of lenses can converge a beam of light coming from outside and focus it to a point on the other side.
WHAT IS lens and types?
There are two types of lensesconvex and concave. Convex lenses are lenses that curve outwards, they converge parallel light rays to a focal point. Concave lenses are thinner in the middle and thicker at their edges. Concave lenses diverge parallel light rays away from each other.
What are the types of lenses in physics?
The two main types of lenses are:
- Convex Lens (Converging)
- Concave Lens (Diverging)
How does a double convex lens work?
A double convex lens, or converging lens, focuses the diverging, or blurred, light rays from a distant object by refracting (bending) the rays twice. This double bending causes the rays to converge at a focal point behind the lens so that a sharper image can be seen or photographed.
Which lens is used in microscope?
A compound microscope uses multiple lenses to magnify an image for an observer. It is made of two convex lenses: the first, the ocular lens, is close to the eye; the second is the objective lens. Compound microscopes are much larger, heavier and more expensive than simple microscopes because of the multiple lenses.
