2:10:30 alt The formula of the magnification is given by, M=IO Where M is the magnification I is the image size and O is the object size. Complete step by step answer: It is given in the problem that a lens is placed between the source of light and a wall. It forms images of area A1 and A2 on the wall for its two different positions and we need to find the area of the source light. The formula of the magnification is given by, M=IO Where M is the magnification I is the image size and O is the object size. Let the sides of the object be a and b then the area of the image will be equal to, ⇒A=ma×mb Where A is the area and m is the magnification of the lens. Let the magnification for the two different positions bem1 andm2 then the multiplication of the two will give us, ⇒m1×m2=1 Area of image for position 1 will be, ⇒A1=m12×(ab)………eq. (1) The area of the image for position 2 will be, ⇒A2=m22×(ab)………eq. (2) Multiplying equation (1) and equation (2) we get, ⇒A1×A2=[m12×(ab)]×[m22×(ab)] Since m1×m2=1 therefore we get, ⇒A1×A2=(ab)2 ⇒ab=Root of A1×A2

[@Parvatham.G]

Nice explanation..what are you doing now?

[@khushi-zd1xi]

1:14:21 this can also be solved by a simple formula R= H/✓u²-1 R being the radius H being the height (4cm) And u being the refractive index 1:58:34 Formula: 1/f = 2(u-1)/R + 1/infinity

1:54:44 There is another solution. The rays converge at f2 after convex lens. If f1=f2, then, then talking with respect to concave mirror, rays incident from f1, will reflect the concave mirror, and become parallel to principal axis. Hence, d= f1+f2 = OPTION A

[@Hrushikesh_LB]

option d is right because concave mirror has negative focal and he made mistake
