We wish to obtain an erect image of an object, using a concave mirror of focal length 15 cm. What should be the range of distance of the object from the mirror? What is the nature of the image? Is the image larger or smaller than the object? Draw a ray diagram to show the image formation in this case.
Answer
Concave mirror gives a virtual and erect image only when the object is placed between its pole and focus.
Hence, the range of distance of the object should be less than 15 cm from the mirror.
Image is virtual.
Image is larger than the object.
Ray diagram to obtain an erect image using a concave mirror is shown below:
