लघुत्तम समापवर्तक (LCM in Hindi)

दो या दो से अधिक संख्याओं का लघुत्तम समापवर्तक वह छोटी से छोटी संख्या हैं जो उन संख्याओं से पूरी विभाजित हो जाती हैं। जैसे:- 4, 8, 12 का लघुत्तम समापवर्तक = 2×2×2×3 = 24,

अतः अभीष्ट लघुत्तम समापवर्तक 24 वह छोटी से छोटी संख्या हैं जो 4, 8, 12 तीनों से पूरी-पूरी तरह विभाजित हो जाती हैं ।

महत्तम समापवर्तक (HCF in Hindi)

दो से अधिक संख्याओं का महत्तम समापवर्तक वह बड़ी से बड़ी संख्या हैं जिसमें वह सभी संख्याएँ पूरी-पूरी विभाजित हो जाती हैं। Ex:- 4, 8, 12 का महत्तम समापवर्तक 4 हैं।

What is mirror, types of mirror and mirror formula class 10th science numerical

What is mirror?

A mirror is a reflective surface that bounces off light, producing either a real image or a virtual image.

Types of mirror

 Mirrors are mainly three types are plane mirrors and concave and convex mirrors.

Concave mirror :-  If the inner side of the spherical mirror is reflecting, it is called a concave mirror. 

Convex Mirror : If the outer side of the spherical mirror is reflecting, it is called a convex mirror.

Characteristics of the image formed by a plane mirror. 

(i) The Image is erect. 

(ii) The Image is of the same size as that of the object. 

(iii) The image is laterally inverted. Right side appears to be left and left side appeared to be right. 

(iv) The image is virtual.

Reflection and refraction of light lens formula Class 10th science Numerical

Lens :- A transparent material bound by two surfaces, of which one or both surfaces are spherical is called the lens.

There are two types of lenses:

i. Convex (Converging) lens- Convex lenses are thick in the middle and thinner at the edges. A convex lens is also known as the converging lens because it converges parallel light rays inwards to a point known as the focal point.

ii. Concave (Diverging) lens- Concave lenses are flat in the middle and thicker at the edges. The concave lens is also known as a diverging lens because it diverges the parallel light rays outward from a point knows as the focal point.

Lens formula:

If u = object distance, v = image distance and

f = focal length of lens,then the lens formula is given by

According to sign conventions we need to assume the distance as follows,

Object distance, u= -ve , Image distance, v = -ve/+ve (depends upon the position of image) and Focal length, f= -ve for concave lens/+ve for convex lens.


Let’s consider following example to understand this formula more precisely.

Ex.1) An object is kept in front of converging lens of focal length 20 cm at distance of 10 cm. Find position of image, nature of image.

Solution: Data given ;( using all sign conventions)

Focal length, f= +20 cm

Object distance, u= -10 cm

Image distance=?


On substituting the above values, we get

∴ 1/v = 3/20

∴ v = 20/3

∴ v = 6.67 cm

Positive value of ‘v’ indicates that image is real but inverted.

Magnification by lenses (M):

Magnification is defined as the ratio of height of image (h2) to the height of object (h1) or the ratio of image distance (v) to object distance (u).

Ex.2) An object of height 5 cm kept in front of convex lens of focal length 25 cm at distance of 10 cm. Find position of image, nature of image and height of the image.

Solution: Data given ;( using all sign conventions)

Height of object, h1= + 5 cm

Focal length, f= +25 cm

Object distance, u= -10 cm

Image distance=?

Image height=?


∴ 1/v = 35/200

v = 200/35

∴ v = 5.7 cm

Positive value of ‘v’ indicates that image is real but inverted.

Now to calculate height of image use 2nd formula

Hence the height of image obtain here will be 2.85 cm.

(3) The distance of object is 20cm from convex mirror of focal length is 25 cm. Find the position of image?


F = 15 => convex mirror

Object distance u = -20 cm

Image distance (v) =?

1/f = 1/v + 1/u

1/25 = 1/v + 1/-20

1/25 + 1/20 = 1/v

45/500 = 1/v

V = 500/45 = 11.11

V = 11.1100

The value of  V is +ve so image is virtual.

(4) The radius of curvature is 38 cm. Find the focal length of convex mirror?


R = 38 cm

Focal length is equal to half of radius of curvature

Focal length = R/2

= 28/2

F = 19 cm

Focal length is 19 cm

(5) Find the position of image if the focal length of convex lens (f) is 8 cm and object is placed 16 cm from lens.


f = 8 cm

u = – 16 cm

v =?

1/f = 1/v – 1/u

1/8 = 1/v – 1/16

1/v = 1/8 – 1/16

1/v = 1/16

V = 16 cm

∴ The image is placed 16 cm from the principal axis.
