The image is always virtual,smaller,and erect at any distance in which the object is placed.
The object should be necessarily be placed between the focal point of the concave mirror and the pole of the mirror to produce a larger image(not larger object) behind the concave mirror.
If an object at is 2.5 cm long is placed on the axis of a concave mirror that is 30 cm radius of curvature at a distance of 10 cm away from it, the position size and nature of the image formed would be 20 cm. This is a math problem.
The concave mirror focusses images to its focal point. So the images formed are real inverted and increases in size as the distance between the aperture and the object decreases. When the object is placed between the focus and the aperture the image formed is virtual erect and magnified.
image distance is the distance from the point of incidence on the mirror, the where the image is reflected to.object distance is the distance from the actual object being reflected to the point of incidence on the mirror where it's reflected as an image.
The image is always virtual,smaller,and erect at any distance in which the object is placed.

A microphone stand allows a microphone to be placed the correct distance, angle and height from a sound source.
Because he just bought a new mirror and had to show it

You need to know the air refractive index and two angles. The first angle is between the incident beam and the line which is perpendicular to the water surface. The second angle is between the transmitter beam (the beam which is the water) and the same perpendicular.
Use 1/s + 1/s' = 1/f s = 20cm f = +10cm (positive since the mirror is concave) 1/s'=1/f - 1/s 1/s'=1/10 - 1/20 = 1/20 So, s'=20cm. The distance from the image to the mirror is 20cm, which is not surprising, since the object placed at 1/2 of the focal length and therefore exactly at the radius of curvature point. The image is real and inverted.
