What is the object distance for a concave mirror?

Click For Summary
SUMMARY

The object distance for a concave mirror is measured along the mirror axis from the object to the vertex of the mirror, which is the center of the concave surface. This measurement is crucial for accurately determining the position of the object in relation to the mirror's focal point and image formation. Understanding this concept is essential for applications in optics and physics.

PREREQUISITES

Hey eveyone,

I have a concave mirror and an object x distance away from the mirror. I am wondering if anyone knows where you measure from in order to determine how far away the object is from the mirror. Is it from the object to the center of the concave mirror?

Thanks,

Yes, the "object distance" is the distance along the mirror axis from the object to the vertex of the mirror (the center of the concave surface).
