A 1.3-cmcm-tall object is 76 cmcm in front of a diverging lens that has a -38 cmcm focal length. A candle flame is placed in front of a concave mirror on the principal axis such that is twice the size of the object and is inverted. Figure 3: The concave mirror on the left forms a REAL image which is INVERTED when the object lies outside the focal point. Also calculate the height of the image formed. (click on the green letters for the solutions). If a real image is formed, image is formed on right side, so image distance is positive. for the given object distance. This calculator makes the complex geometrical calculation very easy by … An object of height 6 cm is placed at a distance of 20 cm from a concave lens. b. You got q=209, a positive number, so h'/h was negative, h' negative, the image was real. So, height of image is 4 cm. Thin Lens Equation: Where: D I = Distance between the image and the center of the lens D O = Distance between the object and the center of the lens F = Focal length: NOTE: The sign convention used is as follows: if D I is negative then the image produced is a virtual image on the same side of the lens as the object itself. 66. h i = m*h o. Thus the magnification is -4. Note: When object is at distance of double of focal length from concave mirror then image of that object is also formed at same point with same height but the image is inverted (check this by equation (2)).
