WebA diverging lens is thicker at the edges than it is in the middle. In a diverging lens light is reflected off an object and travels to a lens. ... S 1 = D −d/2 and S ’ 1 = D +d / 2 Using the thin lens equation, 1/f = (2 / D −d) + (2 D +d) and f = (D 2 −d 2) / 4D Methods/ Procedures 1. Place the screen at a distance D from the ... WebWith a diverging lens, the lens spreads parallel rays out. The focus of a diverging lens is on the same side of the lens as the impinging parallel rays. We will not need concave (diverging) lenses for our study of optics. The thin-lens equation relates the distance of the object from the lens, do, and the distance of the image from the lens, di ...

WebThe treatment of a lens as a thin lens is known as the “thin lens approximation”. Converging lens: Parallel light rays entering a converging lens from the right cross at its focal point on the left (a). Diverging lens: … Web12 Sep 2024 · To properly use the thin-lens equation, the following sign conventions must be obeyed: di is positive if the image is on the side opposite the object (i.e., real image); … WebThe third sample problem will pertain to a diverging lens. Sample Problem #3 A 4.00-cm tall light bulb is placed a distance of 35.5 cm from a diverging lens having a focal length of -12.2 cm. Determine the image distance and the image size.
