The image produced by a convex lens depends on what?
The image depends on the distance the object is from the lens.
What image is formed by a convex mirror?
The image is always virtual,smaller,and erect at any distance in which the object is placed.
How does the distance between an object and a convex lens affect the image formed?
It should appear the same.
When does a convex lens forms a real or virtual image?
When object is within the focal distance then virtual image is formed. But when the object is placed beyond the focus of the covex lens ie if the distance of the object is more than focal length then real image is formed.
What type of image is formed when object is kept at F for a convex lens?
For a convex lens the focal point is the transition point between getting a real image and a virtual image. If the object is at a greater distance then F you get a real image. If the object is closer to the lens then F you get a virtual image. If the object is located at F the light rays from the object leave the lens parallel and never form any kind of image.

The image produced by a convex lens depends upon?
distance from the object

The image formed by a convex spherical mirror will always be what?
The nature of the image is not constant. It varies with the distance between the object and the mirror.

When object is within the focal distance then virtual image is formed. But when the object is placed beyond the focus of the covex lens ie if the distance of the object is more than focal length then real image is formed.

What is the nature of graph of image distance vs object distance for concave mirror and convex lens?
1/a+1/b=1/f
What kind of image is formed by a convex lens when the object at infinity?
The image produced is a real image if the object is located at infinity and the lens is a convex lens. The produced image can actually be placed on a screen and photographed.
An object is located 51 millimeters from a diverging lensthe object has a height of 13 millimeters and thye image height is 3.5 millimetershow far in front of thelens is the image located?
The relation between the distance and height of an object and the image goes like this:L1/H1=L2/H2where L1 and H1 is the Length of the object from the lens and H1 is the height of the object respectively. Same goes for L2, H2 except these are for the image of the same object.If you put values in the above formula, the distance of the image from the lens comes out to be 13.73mm
A convex lens forms a real and inverted image of a needle at a distance of 50cm from the lensWhere is the needle placed in front of the convex lens so that the image is of the same size as the object?
A convex lens forms a real and inverted image of equal size only when it is kept at the center of curvature of the lens. The image is also formed at the center of curvature at the other side. Hence, the distance of object = distance of image = 50 cm. Now, focal length = � � radius of curvature = � � 50 cm = 25 cm Hope it is clear!
