What kind of imagery did Jonathan Edwards use in his sermons? what effect did the great awakening have on the american colonies?.

When the object is located between C and F, the image is located beyond C and is inverted.
| Positions of Object and Image in Concave Mirror | ||
|---|---|---|
| Position of Object | Position of Image | Size of Image |
| Between C and F | Beyond C | Enlarged |
| At F | At infinity | Highly enlarged |
| Between F and P | Behind mirror | Enlarged |
From the above ray diagram we can observe that If we place the object between F(focus)and 2F the image formed is always beyond 2F. The images are real and always inverted.
| Position of object | Position of image | Image Size |
|---|---|---|
| Between F and C | Beyond C | Enlarged |
| At C | At C | Equal to object |
| Beyond C | Between F and C | Diminished |
| At Infinity | At focus (F) | Highly Diminished |
A convex lens is also known as a converging lens. A converging lens is a lens that converges rays of light that are traveling parallel to its principal axis. They can be identified by their shape which is relatively thick across the middle and thin at the upper and lower edges.
Image formed by a convex mirror is always virtual and erect. When an object is placed at infinity, virtual image is formed at focus and the size of the image is smaller.
| Position of the object | Position of the image | Nature of the image |
|---|---|---|
| At C | At C | Inverted and Real |
| Between C and F | Beyond C | Inverted and Real |
| At F | At infinity | Inverted and Real |
| Between F and P | Behind the mirror | Erect and virtual |
The concave mirrors can form two types of images which include- Real and virtual The Real and virtual images are formed by concave mirrors. The images formed can be upright (if virtual) or inverted (if real). Also, the position of the image can be behind the mirror (if virtual) or in front of the mirror (if real).
In fact, it can be generalized that anytime the object is located between C and F, the image will be located beyond the center of curvature as well. In such cases, the image will be inverted and larger in size than the object.
When an object is placed between F and 2F in front of a convex lens, the image formed is magnified, real, inverted and beyond 2F.
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).
Hence, the image formed by a concave lens is always erect and virtual.

| Object Location | Image Location | Image Nature |
| Infinity | At F2 | Virtual and Erect |
| Beyond Infinity and Zero | Between F1 and Optical center | Virtual and Erect |
When they pass through a magnifying glass, the convex lens bends the parallel rays so that they converge and create a virtual image on your eyes’ retinas. … Since the virtual image is farther from your eyes than the object is, the object appears bigger!
So, why do magnifying glasses flip images? Magnifying glasses are constructed and made of convex lenses. Convex lenses primary purpose is to make an object appear larger by dispersing light. Objects will be flipped when the light is focused at a point beyond the lenses focal length for the magnifying glass.
A concave mirror will form a virtual or real image. A convex mirror will only form erect and virtual images. Based on the placement of the object, a virtual or real image will be formed. Convex mirror forms only virtual and erect images irrespective of the position of the object.
A convex lens can form two types of images: (i) real and inverted and (ii) virtual and erect. Real and inverted images are formed when an object is placed beyond the focus of the lens and virtual and erect images are formed when an object is placed between the focus and the optical center.
Yes,convex mirror can form real image when the convergent rays are incident on the mirror. when convergent rays are incident yo convex mirror then the reflected rays intersect at a point in same side of mirror or in front of mirror and form real image.
Detailed Solution. The correct answer is Concave mirror. If the object is placed between the focus and pole of a concave mirror, it provides a virtual enlarged and erect image.
When an object is placed between the focus (F) and optical centre (O) of convex lens, then the image is formed beyond F1 to the same side of as that of object and is erect, virtual and magnified image.
When the object is between F and P of a concave mirror, then its image is formed behind the mirror. The image is enlarged, erect and virtual.
When an object is kept within the focus of a concave mirror, an enlarged image is formed behind the mirror. This image is virtual and erect.
An object is placed in front of a convex lens such that the image formed has the same size as that of the object. An object is placed in front of a convex lens such that the image formed has the same size as that of the object.
If the object is placed between 2F and F, the image will appear beyond 2F on the other side. The image will be real, inverted, and enlarged. For convex lenses, when the object is placed inside F, the image will be on the same side of the lens as the object and it will be virtual, upright, and enlarged.
An infinitely large, real and inverted image is formed at infinity when object is placed at principal focus, F1 of a convex lens. Properties of Image: Image is highly enlarged, real and inverted.
For a converging lens, parallel light rays will converge to a point. This is the focal point (F) of the converging lens. A point that is twice the distance from the lens as the focal point is labeled 2F.
f = focal length. 2f means double of focal length.it is similar to centre of curvature C. 1.
Sample Response: The image created by the object is located on 2F behind the lens, real, inverted, and the same size as the actual object. What happens when the object is placed at F? … Sample Response: No image will be formed because the rays will not converge to or diverge from a common point.

A concave (or diverging) lens forms an upright and diminished image of an object irrespective of its position. The outline ray diagram showing the formation of image is given in figure. For the object AB, the image is A’B’. The image is formed between optical centre O and focus F, in front of the lens.
Lenses may be divided broadly into two main types: convex and concave. Lenses that are thicker at their centers than at their edges are convex, while those that are thicker around their edges are concave. A light beam passing through a convex lens is focused by the lens on a point on the other side of the lens.
On the other hand, the concave side of the spoon acts like a concave mirror. If the spoon is held at arm’s length, the object (you) is farther from the reflecting surface than the center of curvature. As a result, a real image is formed that is inverted and reduced in size with respect to the object.
Therefore, only one image is formed.
