# Properties of image formed by convex mirror

**The object distance is smaller than the focal length of the convex mirror (do < f)**

Based on the calculation of __the image formation by the convex mirror,__ can be concluded that if the object distance (do) is smaller than the focal length (f), the properties of the image are:

– Virtual means the beam of light does not pass through the image because the image is behind the convex mirror

– Upright

– The farther the object is from the convex mirror, the smaller the image size

– The farther the object is from the convex mirror, the smaller the image from the convex mirror

**The object distance is the same as the focal length of the convex mirror (do = f)**

Based on the calculation of __the image formation by the convex mirror__, can be concluded that if the object distance is equal to the focal length of the mirror, the properties of the image are:

– Virtual means the beam of light does not pass through the image because the image is behind the convex mirror

– Upright

– Minimized (Image size = ½ times the object size)

– The image distance is smaller than the object distance (the image distance = ½ times the object distance)

**The object distance is greater than the focal length and is smaller than the radius of curvature of the convex mirror (f < do < R)**

Based on the calculation of __the image formation by the convex mirror__, can be concluded that if the object is between the focal point and the radius of the curvature, the properties of the image are:

– Virtual means the beam of light does not pass through the image because the image is behind the convex mirror

– Upright

– The image size is smaller than the object size

– The farther the object is from the convex mirror, the farther the image from the convex mirror

**The object distance is equal to the radius of curvature of the convex mirror (do = R)**

Based on the calculation of __the image formation by the convex mirror__, can be concluded that if the object distance is the same as the radius of the curvature, the properties of the image are:

– Upright

– Minimized (the image size = 1/3 times the object size)

– The image distance is smaller than the object distance (The image distance = 1/3 times the object distance)

**The object distance is greater than the radius of curvature of the convex mirror (do > R)**

Based on the calculation of __the image formation by the convex mirror__, can be concluded that if the object distance is larger than the radius of the curvature of the mirror, the properties of the image are:

– Upright

– The image size is smaller than the object size

– The image distance is smaller than the object distance (the image is closer to the mirror, the object is farther from the mirror)
