Experiment 1 Measuring the Focal Length of a Convex Lens
10/08/2011 · Does anyone know a simple optical method to determine the focal length (FL) of a concave lens? A method which doesn't require any kind of precision instrument, such a pair of callipers to physically measure the degree of curvature of the glass surface of the lens.... Finding the focal length and the magnification of a lens. Objectives To calculate the focal length of the given lens To find the magnification of the lens Theory Lens is a piece of transparent plastic or glass that has two refracting surfaces which can be either curved on either sides or flat or curved.

- Finding the Focal Length of a Given Convex Lens Aim: - To find the focal length of a given convex lens. Apparatus: - Convex lens Metre rule Screen Candle Matches Wooden blocks Theory:- In this experiment the focal length of a lens is found out. The focal lens of a lens is the distance from the principal focus to the optical centre.... [tags: Papers]... Knowing the focal length of a lens is important in optical fields like photography, microscopy and telescopy. The focal length of the lens is a measurement of how effectively the lens focuses or defocuses light rays.
The Focal Length converging Lens (Displacement Method)
This is a direct relationship between the focal length of the lens and the least distance of distinct vision, or LDDV. The LDDV is the closest your eyes can comfortably look at an object. The LDDV is the closest your eyes can comfortably look at an object.... Experiment 1 - Measuring the Focal Length of a Con...

From Lenses To Optical Instruments Fun Science Gallery
Experiment: To find the focal length (f) of a convex lens by plotting graph between 1/u and 1/v. The relation between the object distance u and the image distance v for a convex lens placed in air is... will be used as a second method of obtaining the focal length of a lens, this time by calculation rather than by direct measurement. As you saw in lecture, the thin-lens equation allows you to find image locations (d i) for lenses that have a thickness much less than the focal length f. Using the thin-lens approximation, a geometric study of light rays may be used, as opposed to the wave-based

- experiment, this limits the measurable focal length to anything below 30 cm. An advantage of this method is that it gives accurate results because the distance, a , is independent of the thickness of the lens and the position of the lens in the lens holder.
- 25/08/2014 · Do Not Forget to Share and Subscribe my Channel To determine the focal length of a convex lens by focusing a distant object CBSE Class 9 Term 2 Experiment 5.
- For a thin double convex lens, refraction acts to focus all parallel rays to a point referred to as the principal focal point. The distance from the lens to that point is the principal focal length f of the lens. For a double concave lens where the rays are diverged, the principal focal length is
- Given that you use the tag "home-experiment" I will give an answer in that spirit. Obviously you can use the convex lens to focus the sunlight onto a piece of paper - find the distance where the paper catches fire and that is your focal length.
