WebFeb 22, 2024 · Consider a thin convex lens of focal length f & R.I (n) placed in air as shown in fig . let R 1 & R 2 → are the of curvature of the surfaces ABC & ADC of the respectively.. O → Luminous point object on the principle axis. A ray OP incident at p, after refraction, emerges along QI & meet at I on the principal axis. WebOF = f, focal length of lens So, v/u = (v-f)/f or, vf - uv = uf or, uv = uf+ vf Divide both sides by uvf, uv/uvf = uvf/uvf + vf/uvf or, 1/f = 1/v + 1/u is the required equation. (ii) Real image (point object method) Consider a …
WebThe signs are reversed for the back surface of the lens: if R2is positive, the surface is concave, and if R2is negative, the surface is convex. Thin Lens Equation Where: DI= Distance between the image and the center of the lens DO= Distance between the object and the center of the lens F = Focal length WebJan 7, 2024 · The derivations are carried out in two parts: (1) the lensmakers' equation of a thin lens for media with different indices (2) generation of the result to the case of the thick lens. As it becomes apparent that the lensmakers equation depends on the refractive indice, not only for the focal distance, but also the terms involving object and ...
WebLens maker’s formula is: = 0.078 Therefore, f = f = 12.82 cm Q.2: Value of the refractive index of lens is 2.5. The curved surfaces are having the radius of curvatures 10 cm and -12 cm respectively. Find out the focal length of the lens. Solution: Given parameters are, = 2.5, = 10 cm and = -12 cm Lens maker’s formula is: = 0.274 So, f = 3.64 cm Web1 do = 0.0333 1 d o = 0.0333. Multiply both sides by do d o and divide both sides by 0.0333 0.0333 to get do d o on its own. 1 0.0333 = do 1 0.0333 = d o. do = 30cm d o = 30 c m. Example 3. A nail is placed a distance of 40cm 40 c m from a diverging lens and an image is produced at a distance of 10.91cm 10.91 c m from the lens.
