Question
The focal length of a concave mirror is 15 cm. An object is located 35 cm in front of this mirror. Where is the image located? Convex mirrors are being used to monitor the aisles in a store. the mirrors have a radius of curvature of 4.0 m. What is the image distance if a customer is 10 m in front of the mirror? Is the image real or virtual? If a customer is 1.5 m tall, how tall is the image? A concave shaving mirror is designed so the virtual image is twice the size of the object. when the distance between the object and the mirror is 15 cm. Determine the radius of curvature of the mirror.Explanation / Answer
12
the mirror equation is
1/f = 1/v + 1/u
for concave mirror, f= -15, u= -35
hence the image distance is
1/-15 = 1/v + 1/-35
v = -26.25 cm
hence, the image is 26.25 cm in front of the mirror.
