Exemplary Mirror Formula Of Lens
Example 103 - A concave lens has focal length of 15 cm.
Mirror formula of lens. The Lens Equation 6 2. This lens formula is applicable to both the concave and convex lens. The image is 375 cm from the lens.
A premiere coaching institute was established in 2007. This means that u and v are on the same side in the case of a mirror and opposite sides in the case of a lens. Mirrors concentrate light and focus all colors of the spectrum in an image.
The magnification is C1C2 25. The image is erect and magnified in size. Image distance v is the length between the image and the pole of the mirror.
Mirror formula for concave mirror when real image is formed Let us take a concave mirror of aperture mirror of aperture XY where a light ray AC is travelling parallel to principle axis from object AB to mirror at C and reflect through focus F and pass through A. It is a virtual image. F focal length of a spherical mirror.
The sign conventions for the given quantities in the mirror equation and magnification equations are as follows. It can be real or. The result is known as the mirror equation for a spherical mirror and from equation 4 the focal length can be found by the following equation f d 0 d i d 0 d i.
Vis the distance of the image from the lens and fis the focal length ie the distance of the focus from the lens. Biconvex glass lens spherical concave mirror meter ruler optical bench lens holder self-illuminated object generally a vertical arrow screen. The focal length is the distance from the focal point to the surface of the mirror or the center of the lens.
