disk of anf/4.5 lens is therefore about 0.0045 millimetre in diameter (ten times the wavelength of blue light). Nevertheless, the Airy disk formed by a telescope or microscope objective can be readily seen with a bright point source of light if a sufficiently high eyepiece magnification is ...

Since the object cannot be placed behind the mirror, we can discard the negative value and conclude that the object can be placed at a distance of 9 cm from the mirror to produce an image that is five times its size. To find the second location, we can use the magnification formula, ...
Magnification of the real Image is considered negative and that of the virtual Image is considered positive. THINGS TO REMEMBER IN THIS CHAPTER Concave Lenses are used in eyeglasses and contacts, flashlights, photography etc. Lens formula - 1/v-1/u=1/f ...
Formula symbol: f DOI: 10.61835/ldf Cite the article: BibTex plain textHTML Link to this page LinkedIn Various types of optical systems (e.g. microscope objectives and curved laser mirrors) can focus or defocus light, and the focal length is used for quantifying such effects. The simplest ...
In your case, if the focal length (f), distance of object (do), and distance of image (di) are given, you can use the formula 1/f = 1/do + 1/di to find the magnification. Once you have the magnification, you can use the above equation to find the height of the image. I ho...
