American Buddhismâs numbers are booming. Published just over three years ago, an American Religious Identification Survey survey showed that from the years 1990 to 2000, Buddhism grew 170 percent in North America.
However, for a lens, a positive image distance implies that the image is located on the opposite side as the object. Virtual images are formed by concave lenses or by placing an object inside the focal length of a convex lens. The ray-tracing exercise is repeated for the case of a virtual image. In this case the virtual image is upright and shrunken. The same formula for the image and object distances used above applies again here.
Question 2: Find the size of the image from relation of the linear magnification of lens, the size of the object is 1 cm is place at a distance of 15cm from a concave mirror and the image is formed at a distance 30cm on the side of the object.Solution:r. In terms of image distance (v) and object distance (u), the linear magnification is equal to the ratio of the image distance to the object distance. m = $\frac{v}{u}$ If m is positive, then the image is erect and when m is negative the image is inverted.
