- A spherical mirror is to be used to form an image, five times as tall as an object, on a screen positioned 4.2 m from the mirror. (a) Describe the type of mirror required. The mirror is a ---Mirror Type--- mirror and it has a focal length of m. (b) Where should the mirror be positioned relative to the object? The object should be m in front of the mirror.A convex mirror with a radius of curvature of -29.0 cm is used to form an image of an arrow that is 10.2 cm away from the mirror. If the arrow is 2.40 cm tall and inverted (pointing below the optical axis), what is the height of the arrow's image? (Include the sign of the value in your answer.) cmA dentist uses a mirror to examine a tooth. The tooth is 1.14 cm in front of the mirror, and the image is formed 12.7 cm behind the mirror. Determine the mirror's radius of curvature.
- Suppose a man stands in front of a mirror as shown in Figure. His eyes are 1.65 m above the floor, and the top of his head is 0.18 m higher. (a) Find the length of the smallest mirror in which he can see both the top of his head and his feet and its height above the floor. Length of the mirror: Height from floor to bottom of mirror: Height from floor to top of mirror: m (b) How is the mirror length related to the man's height? m m The mirror length is the man's height.Please help me with number 23A student attempts to determine the focal length of a mirror through graphical analysis. They make a series of observations by changing the position of an object and measuring the position of the corresponding focused image. When they graph their data to create a linear relationship, they obtain the following graph. (T-W) 'P/T 4.5 4 3.5 3 2.5 2 1.5 1 0.5 0 0 0.5 Observations of a Converging Mirror 1 1.5 2 1/d, (m¹) 2.5 3 3.5 4 4.5 Based on their graph, the best value for the focal length of the mirror, in meters, to two significant digits is:
- 6. Two students in a physics laboratory each have a concave mirror with the same radius of curvature, 38.0 cm. Each student places an object in front of a mirror. The image in both mirrors is three times the size of the object. However, when the students compare notes, they find that the object distances are not the same. What is the distance of the farther object? cmA man stands in front of a mirror as shown in the figure below. His eyes are 1.78 m above the floor, and the top of his head is 0.13 m higher. Find the height above the floor of the top and bottom of the smallest mirror in which he can see both the top of his head and his feet. top m bottom m How is the distance d from the top to the bottom of the mirror related to the man's height h? d =A man stands in front of a mirror as shown in the figure. His eyes are 1.70 m above the floor, and the top of his head is 0.13 m higher. Find the height above the floor of the top and bottom of the smallest mirror in which he can see both the top of his head and his feet. top 1.765 bottom 0.85 m m How is the distance d from the top to the bottom of the mirror related to the man's height h? Use the symbol h to represent the man's height. d = 0.915 X How is the length of the mirror related to the distance from the floor to the top and bottom of the mirror?h
- A woman is 2 m tall, with her eyes at a height of 1.83 m. A mirror is on the wall, ending somewhat higher than her head. What is the highest point above the floor the bottom of the mirror can be so that she can still see her feet? You Answered 0.557 Correct Answer 0.915 margin of error- 1%You are comparing two convex mirrors, both to be used in air. The first mirror has aradius of curvature of 1.2m and the other of 2.3m. Calculate the focal length of each mirror.Which one has the longer focal length?20. In E111, the object is placed in front of a convex mirror, at an object distance equal to the magnitude of the focal length. Which of the following is the image formed? The image is half as large as the object and located at twice the object’s distance behind the mirror. The image is half as large as the object and located at half the object’s distance behind the mirror. The image is twice as large as the object and located at half the object’s distance behind the mirror. The image is twice as large as the object and located at twice the object’s distance behind the mirror.
