How does the object distance of a convex lens compared with the object distance of a concave lens?
The object distance of a convex lens is measured from the optical center to the object, while for a concave lens, it is measured from the optical center to the object along the path of light. In general, the object distance for a convex lens is positive, while for a concave lens, it is negative since the object distances are measured on the opposite sides of the lens.

What is the nature of graph of image distance vs object distance for concave mirror and convex lens?
For a concave mirror, the graph of image distance vs. object distance is typically parabolic. As the object distance increases, the image distance initially decreases and then increases. For a convex lens, the graph is also parabolic with similar characteristics, as the image distance changes with respect to the object distance following a curved path.
Is a mold convex or concave?
A mold is typically concave, as it forms the negative space of the object being molded. This allows the object to be shaped and formed according to the contours of the mold when the material is poured or pressed into it.
Write magnification relation in terms of you and v for convex lens and concave mirror?
Convex is () and makes objects appear larger. Concave is )( and makes objects appear smaller. The side rear-view mirrors on cars have concave mirrors, hence, "Object are closer than they appear." Easy way to remember is that a cave is like a hole in the ground, so something is concave if it gets smaller towards the center.
Is it possible to find whether a mirror is plane concave or convex from the nature of image of an object?
Yes possible. If we place an object somehow close to the mirror and observe the image. If the image is of the same size as that of the object then it is a PLANE mirror If the image is magnified and erect, then it will be a concave mirror If the image is dimisnished then the mirror is convex in nature.
What are the three kinds of mirrors and what kind of images do they reflect?
The three kinds of mirrors are plane mirrors, concave mirrors, and convex mirrors. Plane mirrors reflect a virtual image that is upright and the same size as the object. Concave mirrors reflect both real and virtual images, depending on the object's position relative to the mirror. Convex mirrors always reflect virtual images that are smaller and upright.

What is important in concave and convex mirror?
In concave mirrors, the focal point, focal length, and magnification are important. Concave mirrors can form real or virtual images depending on the object's position relative to the mirror. In convex mirrors, the field of view and image size are important. Convex mirrors always produce virtual images that are smaller and upright compared to the object.

To magnify an object would you use a convex lens or a concave lens?
You would use a convex lens.
Is it possible to find whether a mirror is plane concave or convex from the nature of image of an object?

Why Describe two ways using convex and concave lenses to form and image that is smaller the the object?
Using a convex lens: When an object is placed between the focal point and the convex lens, the image formed will be virtual, upright, and smaller in size. Using a concave lens: Placing an object further away from the concave lens than its focal point will result in an image that is virtual, upright, and smaller than the object.
What is formula for concave lens?
The formula for a concave lens is the same as for a convex lens, which is given by the lens formula: 1/f = 1/v + 1/u, where f is the focal length of the lens, v is the image distance, and u is the object distance. For a concave lens, the focal length is considered negative.
How can you distinguish between a plane mirror concave mirror and a convex mirror by merely looking at the mirror?
If our image is real and inverted and smaller than the object ,then it is a concave mirror; if the image is virtual and erect and larger than the object,then it is a convex mirror; if the image is of the same size as of the object,it is a plane mirror. that is how we can distinguish or identify which of the given mirrors are what. BUT if the angle is very small you cannot tell Plane is flat, convex it curves outwards and concave it curves inwards.
Describe the images formed in a concave mirror and in a convex mirror?
Here is a description of image formation in a concave mirror: if the object is beyond the center of curvature (F), the image formed is real and upside down; if the object is very near to the concave mirror, the image forms behind the mirror. It is virtual, upright, and bigger in size. Here is a description of image formation in a convex mirror: a convex mirror always produces a virtual, upright, and smaller image of the object at any distance in front of it. The image is located behind the mirror.
What is position of focus point in convex mirror and concave mirror?
In a convex mirror, the focus point is located behind the mirror, on the same side as the object. In a concave mirror, the focus point is located in front of the mirror, on the opposite side of the object.
