When using the Lens Equation, a real object has a:

a) positive image distance

b) positive object distance

c) negative image distance

Answer: When using the Lens Equation A real object always has a positive object distance.

## Explanation

The lens equation is a significant topic in physics and optics because it quantifies the connection between an object and its picture. In a lens equation, there are three important elements: distance of the object from the camera, image distance, and focal length.

The distance between an object and the point where light rays strike the lens is known as the object distance.

The image distance is the distance between the lens and the picture.

The focal length of a lens is the distance between the center of the lens and its focal point.

If you’re using a real object, the distance between it and the lens will be positive because it is in front of a lens. Image distance can be both true (if an image is genuine) and false (if an image is false).
