Three lenses L_1,L_2,L_3 each of focal length 30 cm are placed co-axially as shown in (Fig. 11(b).57). An object is held at 60 cm from the optic centre of lens L_1 . The final real image is formed at the focus of L_3 . Calculate separation between (i) L_1 and L_3 (ii) L_2 and L_3 ? .
The bar chart represents number of fiction and non -fiction books in four libraries L1,L2,L3 and L4 .Consider the bar chart and answer questions based on it . The ratio of total books of libraries L1 and L3 to L2 and L4 is A. 29/36 B. 36/29 C. 36/31 D. 32/33
Three energy levels L_1,L_2 and L_3 of a hydrogen atom correspond to increasing values of energy i.e., E_(L_1) lt E_(L_2) lt E_(L_3) . If the wavelength corresponding to the transitions L_3 to L_2, L_2 to L_1 and L_3 to L_1 are lambda_3, lambda_2 and lambda_1 respectively then
You are given three lenses L_1,L_2 and L_3 each of focal lenth 15 cm.An object is kept at 20 cm in front of L_1 as shown in Fig.2.87. The real image is formed at the focus I of L_3 .Find the separations between L_1,L_2 and L_3 . .
There are p,q,r points on three parallel lines L_1,L_2 and L_3 respectively, all of which lie in one plane . The number of triangle which can be formed with vertices at these points is :
