Answer 1

, located at is om to pole' we con cave ) It 1 = mirror is v conscaleft side of the pole. In this question given that image of object ( dung beetle ) located at focal length of Spherical minor is 25 cm (a) now Calmente distance of object from the Sperical minor In this question spherical minor not specified Or Convex. so We take Cancane miroz here Now we know that the formula f so +15 cm 1 so objet Scanned with CS u fe focal length of concave Posittee Megative u distance of object from pole V o distance of image from pole V here f = #25cm VE u = ? ㅗ - is ll El 25 4 u= -9.375 cm doslemce at 09.375 on clistance will be

EP t object image (6) to be Shorter The dunge bettle height appear than of its image. We know that formula of magnification wright of image height of Object (h) (ha) mo -V u 15 h -9.375 hi his 9.375 hz hot do IS so we say that that object will be shorter than image. CS Scanned with CamScanner

(6) In above picture giren Convex lens and object given centre op lens and focus the object object between the image using rays for the object will be like so as below diagram. shoul & F Object CS Scanned with CamScanner . IN
