Physics formulas for class 10 are based on CBSE (NCERT). Magnification in lens. These distances are measured from the optical centre of the lens. Refractive Index = (Speed of Light in Vacuum)/(Speed of Light In Medium) Delta δ=(i¹ + i²) – (r¹ +r²) r¹ +r² =A. These physics formulas will not only help class 10 students to prepare for their class 10 board exams but also in their later stages when they set out to prepare for competitive medical and engineering entrance exams like NEET and JEE. ... Class 10. 13 0 obj >> The angle of incidence is equal to the angle of reflection i.e., $\angle i=\angle r$. i¹ + i² =A + δ. δ(min) = 2 i-A Chapter-5 Refraction through a lens. The object distance $u$, image distance $v$ and focal length $f$ are related by the mirror formula: $$\frac{1}{v}+\frac{1}{u}=\frac{1}{f}$$, The magnification is the ratio of image height to the object height and it is given by $$m=-\frac{v}{u}$$. The object distance u u, image distance v v and focal length f f are related by the mirror formula: 1 v + 1 u = 1 f 1 v + 1 u = 1 f. The magnification is the ratio of image height to the object height and it is given by m = − v u m = − v u. Focal length is equal to half of radius of curvature i.e., f = R/2 f = R / 2 . �k�+�Z�L��g� �HBk�7���u�R1�WF�(w�V)��x\�HS�~#xIT;V�`-�'�9%�AIs�[^��C1�_ ��&�/�$o�+D���̣�M!��Z�=�)��[��=�׫�T�c���޼W���̣�M!�]-zET����}V�O㍁j�}��N�;*�a��r7o�+%_��$��W��J�L����Q�/V:��^ņb4�FETK����C���-[)I�_���R�tT���$v�N�[�lV4t�\!v2�;�u��D��G���х����2�����Q��f�WTUs�ҵ�_4�7�K�P���^��b�궋.[���Rz5������;5U%}.
