We always want to share our feelings with ours. We need someone who can listen to us. But is not easy to find such a person. Everybody can not be patience listeners. However, there is one with whom everybody or anybody can share his feelings. It is one who is more patience than all people. Yes it is paper. It has more patience than people. It will receive whatever we have to say and it will never tell our secret to anyone unless we wanted. That was why Anne Frank says paper has more patience than people...........

NCERT Solutions for Class 10 Chapter 10 Image 7 The image is located at a distance of 6 cm from the mirror on the other side of the mirror. The positive and a value of less than 1 of magnification indicates that the image formed is virtual and erect and diminished. 13. The magnification produced by a plane mirror is +1. What does this mean? Answer- The positive sign means an image formed by a plane mirror is virtual and erect. Since the magnification is 1 it means that the size of the image is equal to the size of the object. 14. An object 5 cm is placed at a distance of 20 cm in front of a convex mirror of radius of curvature 30 cm. Find the position, nature and size of the image. Answer- Object distance (u) = – 20 cm Object height (h) = 5 cm Radius of curvature (R) = 30 cm Radius of curvature = 2 × Focal length R = 2f f = 15 cm According to the mirror formula, NCERT Solutions for Class 10 Chapter 10 Image 8 The positive value of image height indicates that the image formed is erect. Hence, the image formed is erect, virtual, and smaller in size. 15. An object of size 7.0 cm is placed at 27 cm in front of a concave mirror of focal length 18 cm. At what distance from the mirror should a screen be placed so that a sharply focused image can be obtained? Find the size and nature of the image. Answer- Object distance (u) = – 27 cm Object height (h) = 7 cm Focal length (f) = – 18 cm According to the mirror formula, NCERT Solutions for Class 10 Chapter 10 Image 9 The negative value of image height indicates that the image formed is inverted. 16. Find the focal length of a lens of power -2.0 D. What type of lens is this? Answer- Power of lens (P) = 1/f P = -2D f = -1/2 = -0.5 m A concave lens has a negative focal length. Therefore, it is a concave lens. 17. A doctor has prescribed a corrective lens of power +1.5 D. Find the focal length of the lens. Is the prescribed lens diverging or converging? Answer- Power of lens (P) = 1/f P = 1.5D f = 1/1.5 = 10/15 = 0.66 m A convex lens has a positive focal length. Therefore, it is a convex lens or a converging lens.

Magnetic field lines appear to emerge or start from the north pole and merge or terminate at the south pole. Inside the magnet, the direction of the magnetic field lines is from the south pole to the north pole. Magnetic field lines never intersect with each other. Magnetic field lines form a closed-loop.

Siddharth Singh 3 years, 3 months ago

Some Properties of magnetic field lines are :- 1) They Never Intersect each other . 2) Originate from north pole and end at south Pole. 3)The More curves will be there in magnetic field lines the stronger will be it's magnetic field. 4)They Are like Closed Curves,As they end at a point . 5)They are crowded at the poles that is why there is maximum magnetic attraction 🧲 at The poles

Mahi Yadav 3 years, 3 months ago

1 They travel North Pole to South Pole outside the magnet and South Pole to North Pole inside the magnet. 2 They are closed and continues curves.

Prajwal K 3 years, 3 months ago

1. They r parallel 2. Never meet each other 3.Magnetic force is maximum at the poles 4. They flow from south pole to North pole
