When the object is placed at 2F in front of convex lens image is formed at?
When the object is placed at 2F in front of a convex lens, the image is formed at 2F on the other side of the lens. This is known as the "2F" image formation of a convex lens. The image is real, inverted, and the same size as the object.
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
What are the images formed by 2F?
For a converging lens, the image formed by the 2F position is real, inverted, and smaller in size compared to the object. It is located at a distance equal to two times the focal length of the lens on the opposite side of the lens from the object.
Function of the convex lens?
Function of Convex lens: Convex lens causes parallel rays of light to converge after refraction. Also the following can also be considered as the functions of convex lens: 1.when the object is at infinity, convex lens forms the image at focus which is real and inverted. 2.when the object is beyond 2F, image is formed between F and 2F which is real, inverted and diminished. 3.when the object is at 2F ,image is formed at 2F,which is real , inverted and of same size. 4.when the object is between F and 2F, image is formed beyond 2F which is real,inverted and magnified. 5.when the object is at F,image is at infinity which is real inverted and very much magnified. 6.when the object is between F and C, image is formed beyond 2F and behind the object which is virtual, erect and magnified.
What type of image formed by a convex lens is determined by the objects?
When the object is located at a location beyond the 2F point, the image will always be located somewhere in between the 2F point and the focal point (F) on the other side of the lens. Regardless of exactly where the object is located, the image will be located in this specified region. In this case, the image will be an inverted image. That is to say, if the object is right side up, then the image is upside down. In this case, the image is reduced in size.

where will be image form in concave lens when object is placed at focal lenth?
When the object is located at a location beyond the 2F point, the image will always be located somewhere in between the 2F point and the focal point (F) on the other side of the lens.

How do you derive relation between focal length and radius of curvature of concave mirror?
Consider a ray of light AB, parallel to the principal axis, incident on a spherical mirror at point B. The normal to the surface at point B is CB and CP = CB = R, is the radius of curvature. The ray AB, after reflection from mirror will pass through F (concave mirror) or will appear to diverge from F (convex mirror) and obeys law of reflection, i.e., i = r. From the geometry of the figure, If the aperture of the mirror is small, B lies close to P, BF = PF or FC = FP = PF or PC = PF + FC = PF + PF or R = 2 PF = 2f or F=R/2 or 2F=R Hope this helps............

When object is positioned at more than twice the focal length of a convex lens what are the properties of its image?
When the object is positioned at more than twice the focal length of a convex lens, the image formed is real, inverted, and smaller in size. The image is formed between the focal point and the optical center of the lens.
Can convex lens have real and magnified image?
Yes it is possible. When the object is kept in between F and 2F, then an enlarged real but inverted image is got beyond 2F on the other side of the lens.
Is the focal length of a concave mirror is half the radius of curvature?
As shown in the figure, a paraxial ray is incident at point Q on a concave mirror. q = angle of incidence = angle of reflection = Ð CQF = Ð QCF ( by geometry ) So, for D CFQ, exterior Ð QFP = Ð CQF + Ð QCF = 2q . For paraxial incident ray and small aperture, CP' » CP = R and FP' » FP = f. For small aperture, 2q is very small. \ from the figure, 2q » FP QP = f QP … ( 1 ) and q = CP QP = R QP … ( 2 ) From equations ( 1 ) and ( 2 ), R = 2f ⇒ f = R / 2 Thus, focal length of a concave mirror is half its radius of curvature.
What does the letter z stand for in physics?
IMAGE: Size (smaller, larger, same). Attitude (Upright, inverted). Location (beyond 2F, between F and 2F, same side of object) note: if image is at F, there will be no SALT because there won't be a clear image. Type (Real- can be formed on the screen and light rays meet after refraction, Virtual-cannot be formed on the screen and light rays do not meet after refraction).
How diverging lens can produce images that are smaller than the object?
When the object is located at the 2F point, the image will also be located at the 2F point on the other side of the lens. In this case, the image will be inverted (i.e., a right side up object results in an upside-down image). The image dimensions are equal to the object dimensions. A six-foot tall person would have an image that is six feet tall; the absolute value of the magnification is exactly 1. Finally, the image is a real image. Light rays actually converge at the image location. As such, the image of the object could be projected upon a sheet of paper.
