Here, h is the height of image and h’ is the height of the object. Magnification is also equal to the …
WebFocal length (f) : The distance of the principal focus (F) from the pole (P) of the spherical mirror is called the focal length. It is denoted by the letter ‘f ‘. The relationship between the image distance (v), object distance (u) and focal length (f ) of a spherical mirror is known as the mirror formula. The Mirror formula can be written as : WebTherefore, the focal length of the spherical mirror is 10 cm. 3. Name the mirror that can give an erect and enlarged image of an object. ... According to the mirror formula, The positive value of image height indicates that the image formed is erect. Hence, the image formed is erect, virtual, and smaller in size.
