Hint: what equations do you know that relate the size of the object to the size of the image?
Libra_girl said:Is it the equation: do/di = m or 1/do + 1/di = 1/f ?
tiny-tim said:Both equations!
Except isn't it m = -di/do?
Libra_girl said:yeah it is sorry

The distance between the object and the lens refers to the physical distance between the object being observed and the lens of the device used to observe it. This can also be referred to as the focal length.
The distance between the object and the lens is important because it affects the image produced by the lens. A shorter distance can result in a larger and more magnified image, while a longer distance can result in a smaller and less magnified image.
The distance between the object and the lens is typically measured in millimeters (mm) using a ruler or measuring tape. It can also be measured using specialized equipment such as a caliper or a laser measurement tool.
Yes, the distance between the object and the lens can be changed by physically moving the lens closer or further away from the object. Some devices also have adjustable focal lengths that allow for changes in the distance between the object and the lens.
The distance between the object and the lens can greatly affect the quality of the image produced. A shorter distance can result in a sharper and more detailed image, while a longer distance can result in a blurrier and less detailed image. Additionally, the distance can also affect the depth of field and focus of the image.
