WebThe focal length of the thin bi-convex (converging) lens was measured using the same methods as above, with the screen moved until the sharpest image was seen and p and q were measured and recorded in Table 3. Then the compound focal length for the two converging lenses was measured with? = 2𝑓 ̿ 1 𝑓 2 𝑓 ̅ 1 +𝑓 2. WebThe focal length of a thin lens is related to the radii of curvature of its two surfaces. 1/f = (n2 - n1)(1/R1 - 1/R2). Details of the calculation: Both R1and R2are positive. Therefore 1/f = (n2 - n1)(1/R1 - 1/R2) f = 20 cm. The …
WebThe simplest case is where lenses are placed in contact: if the lenses of focal lengths f 1 and f 2 are "thin", the combined focal length f of the lenses is given by = +. Since 1/f is the power of a lens, it can be seen that the powers of thin lenses in contact are additive. WebThe thin lens Reasoning: We can use the lens equation, 1/xo+ 1/xi= 1/f, and M = -xi/xoto solve the problem. Details of the calculation: Given: A real image implies a converging lens, the image is inverted, f is positive, M is …
