Infer this information for both the lens and mirror based on the data collected. Report these ranges in terms of f and/or 2f. For example, “When do is less than 2f.”
- An object is placed 30 cm in front of a diverging mirror having a focal length of magnitude 20 cm. What is the image distance, in cm? Your answer needs to have 2 significant figures, including the negative sign in your answer if needed. Do not include the positive sign if the answer is positive. No unit is needed in your answer, it is already given in the question statement.Spherical mirrors. Object O stands on the central axis of a spherical mirror. For this situation object distance is ps = +15 cm, the type of mirror is convex, and then the distance between the focal point and the mirror is 30 cm (without proper sign). Find (a) the radius of curvature r (including sign), (b) the image distance i, and (c) the lateral magnification m. Also, determine whether the image is (d) real or virtual, (e) inverted from object O or noninverted, and (f) on the same side of the mirror as O or on the opposite side.

- Thin lenses. Object O stands on the central axis of a thin symmetric lens. For this situation, each problem in the table (below) gives object distance p (centimeters), the type of lens (C stands for converging and D for diverging), and then the distance (centimeters, without proper sign) between a focal point and the lens. Find (a) the image distance i and (b) the lateral magnification m of the object, including signs. Also, determine whether the image is (c) real or virtual, (d) inverted from object O or noninverted, and (e) on the same side of the lens as object O or on the opposite side.

- I continue to get the wrong answer. TIA.The image of the Moon is formed by a concave mirror (aka telescope) whose radius of curvature is 9.62m at a time when the Moon's angular diameter is 0.523degrees. What is the diameter (magnitude only) of the image (cm) of the moon? HINT: What is the property of the rays coming from one point on the edge of the Moon (think of the moon as being infinitely far away)? Where do those rays converge to form an image of that point? Use the small angle approximation: sin(x)=tan(x)=x for |x|<<1, when x is measured in radians.Your friend has glasses. When you look stralght at their eyes when they are wearing glasses, you notice that their eyes appear right-side up and 1.1 times larger in height (and width) compared to when they are not wearing glasses. Assume that their glasses are 2.0 cm away from their eyes. What is the focal length of their glasses? Hint: What Is the object and where is the image?
