i do not think so because a mirror an a lens is two same things except that mirrors can reflect the water and the lens may refract or bend the water so that can change the focal length between the mirror and the lens

Where should the object be placed in order to produce a larger object behind a concave mirror?
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.
A bus driver looks into a plane mirror 20 cm long which is placed 50 cm in front of him if the rear window is 500cm away from the plane mirror through what length of the rear window can he see whene?
The answer is 50 times the mirror added by 500 and sbtract by X and divide by 2 and also you ned to destroy the whole universe and eat your food b
A man of height 1.4m wishes to see his full image in a plane mirror placed at distance 2m what should be the minimum height of the mirror?
0.7
A candle is placed between the center of curvature and the focal point of a concave mirror?
Real, Enlargened
Which position of the object will produce an image of the same size as the object?
In case of reflection at a concave mirror as the object is placed at its center of curvature we get the same size And in case of lens, as object is placed at 2F, we get same sized image
Do the objects size change when its placed at the focal length of the concave mirror?
The objects size is not going to change. The image size, however, would.
Which mirror show virtual image of object placed in front of it?
Plane Mirror And Other Spherical Mirrors Bulged Outside, Such As Convex Mirrors
When an object is placed 8 millimeters from a concave spherical mirror a clear image can be projected on a screen 16 millimeters in front of the mirror. If the object has a height of 4 millimeters the?
c. 8 millimeters
A converging mirror has a focal length of 20cm Where should an object be placed so that its virtual image will be twice as tall as the object?
10cm
What is the focal length of a mirror when it is placed in water with respect to air?
The focal length remains the same because only refraction is affected by the different media. Reflection does not depend on the media.
What shape is a concave mirror and what do things look like in it?
A concave mirror bulges away from the incident light. The image of an object depends on where exactly the object is placed - relative the to focal length of the mirror. See the attached link for more details.

A candle is placed on the principal axis of a concave mirror at a distance of 20 cm from the mirror the focal length of the mirror is 10cm the image formed will be?
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.
