(chatquestion)...48 • Optics and Modern Physics Type 6. To find a rough image of a square or rectangular type of object kept along the axis Concept (i) If object is towards Por C, then its image is also towards P or C. (ii) If object is towards F, then its image is towards infinity and it is more magnified Slu O Example 7 A square mnqp is kept between F and C on the principal axis of a concave mirror as shown in figure. Find a rough image of this object. Solution Object is placed between F and C, therefore, image is real, inverted magnified and beyond C. Further pq is towards F. Therefore, its image p d is towards infinity and it is more magnified. A rough image is as shown alongside. For Usi Sol Fo Us From the ray shown in figure, we can see that n' g will be a straight line. Exercise In the given problem, focal length of mirror is 30 cm and side of square is 10 cm with pP = 40 cm. Find perimeter of the image Ans (90 + 15/10) cm We Note h Type 7. Two mirror problems Type 8. How to Concept If an object is placed between two mirrors, then infinite reflections will take pla Therefore, infinite images are formed. But normally position of second image is asked, S we have to apply mirror formula two times. Image from first mirror acts as an object for t second mirror. Sign convention for second reflection will change but sign of focal lengthw not change. With abov O Example 8 Focal length of convex mirror M, is 20 cm and that of concave mirror M, is 30 cm. Find position of second image I,. Take first reflection rom M. M1 M2 20 ст 10 cm...(Ques near pink mark)
