7. Write the thin lens equation. Explain each symbol and sign convention
Added by Thomas E.
Step 1
- u = object distance from the lens (distance measured from the lens to the object along the incident light direction; with the Cartesian sign convention used here, distances measured to the left of the lens are negative and to the right are positive; for a real Show more…

2. Write and describe thin lens equation, lens make's equation, and magnification equation. Give the meaning of positive or negative sign for each quantity. 3. A converging lens has magnitude radius of curvature R = 0.78 m for both surfaces and refractive index n = 1.60. An object is placed 35.0 cm from the lens. Find focal length f, the image distance q, magnification M, and describe the image. 4. Two thin lenses of one converging lens f1 = 30.0 cm and one diverging lens f2 = -20.0 cm are separated by d = 10.0 cm as illustrated in the figure. An object is placed 45.0 cm to the left of lens Find the position and the magnification of the final image.
9) Draw and explain sign conventions for convex lens.
