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:

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

– 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:

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