An object is placed 15 cm from a converging ( concave ) mirror that has a focal length of 10 cma. determine the image located b. determine the magnification factor c. if the object is 5 cm high how high is the image d. what are the four characteristics of the image plz try to answer faster

★ Ello ★

here is your answer !!


u = -15 cm


f = -10 cm.



v = ??


using the MIRROR formula we have


1 / u + 1 / v = 1 / f


= > 1 / -15 +1 / v = 1 / -10



=> 1 / v = 1 / -10 + 1 / 15

= > a =>>> v = -30 .


now ,

=>>>> B



magnification =>. - v / u

=>. -30 / 15

=> - 2


D ))) hence , the magnification is NEGATIVE then we know that image is :-


real and inverted




C )))





height of image => ??





height of object = 5cm



magnification = image HIGHT / object height



=> -2 = image distance / 5


hence , image distance is => 10 cm





thanks
