1.	6. An object 4 cm in size is placed at a distance of 25 cm from a concave mirror of focal length 15 cm. Find the position, nature and height of the image.
Answer» tion:Height of object- 4cm (ho)Object Distance- -25 cm (u)Focal Length- -15cm (F) Using MIRROR FORMULA, 1/f - 1/u = 1/v -1/15 + 1/25 = 1/v - 5 +3/ 75 = 1/v -2/75 = 1/v v= -75/2 = -37.5 So, the image will form on the same side of the object placement. m= -v/u = HI/ho -(-37.5)/-25 = hi/4 - 1.5 x 4 = hi hi= -6 cm So, the image formed is real, inverted and highly magnified. Image Height is 6 cm.
