And is written as : \( \frac{1}{v} + \frac{1}{u} = \frac{1}{f} \) This formula is valid for all kinds of spherical mirrors, for all positions of the … WebMar 19, 2024 · On dividing the above equation, then $\Rightarrow f = 7.5\,cm$ The radius of curvature is equal to the two times of the focal length. $\Rightarrow R = 2f$ By …
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 : WebQ10. Suppose you want to observe an erect image of a candle flame using a concave mirror of focal length 20 cm 20\ \text{cm} 2 0 cm 20, space, start text, c, m, end text. State the range of distance of the candle flame from the mirror. List two other characteristics of the observed image. Draw a ray diagram to show the formation of image in ...
WebA spherical mirror has a radius of curvature R and a focal length f = R/2. The focal length f is the distance between the focus and the surface of the mirror. The figure on the right compares a parabolic and a concave spherical surface with the same focal length f. Near the symmetry axis or optical axis the curves are nearly identical. WebSolve the mirror equation for the focal length f and insert the known values for the object and image distances. The result is The result is 1 d o + 1 d i = 1 f f = ( 1 d o + 1 d i ) −1 = …
