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.
Why is the focal point of a convex lens real and that of a concave lens virtual?
The focal point of a convex lens is real because light rays actually converge at that point after passing through the lens. In contrast, the focal point of a concave lens is virtual because the light rays appear to diverge from that point, but they do not actually pass through it.
Can a concave mirror act as a convex mirror?
No, a concave mirror and a convex mirror have different curvatures and focal points. A concave mirror reflects light inward, converging it to a focal point, while a convex mirror reflects light outward, diverging it. They cannot interchange their functions.
Why it is easier to find the focal point of convex lens than concave lens?
It is easier to find the focal point of a convex lens because the focal point is on the same side as the incoming light, making it more accessible to measure. In contrast, for a concave lens, the focal point is behind the lens and is virtual, making it harder to locate experimentally.
Five difference between a concave mirrors and convex mirrors?
Concave Vs Convex 1. Mercury coating will be made on the convex side but here on concave side. So reflecting portion would become concave and here convex 2. Both real and virtual images but only virtual images 3. Both diminished, enlarged and even same size images formed but only diminished. 4. Both inverted (real) and erect (virtual) images but only erect images. 5. Used as shaving mirror and in telescopes but used as rear view mirror
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.
Why is a focal point of a convex lens real and that of a concave lens virtual?
because in a convex lens rays join at a common point after refrection but in case of a concave lens they appears to come from a common point.
What kind of lens can be used to produce a virtual image?
Convex lens produces both real and virtual images. But concave lens produces only virtual images for real objects. If object is virtual then real image could be produced by a concave lens.

Name two types of curved mirrors?
Concave mirrors and convex mirrors are two types of curved mirrors. Concave mirrors converge light rays to a focal point and can form real or virtual images. Convex mirrors diverge light rays and produce virtual, upright, and diminished images.

Why focal length of convex lens is easier to find than a concave lense?
The focal length of a convex lens is easier to find than a concave lens because for a convex lens, the focal length is positive and is measured from the lens to the focal point. In contrast, for a concave lens, the focal length is negative and the rays of light are diverged. This makes it more challenging to find the focal point accurately.
What is the difference between the virtual image formed by a convex lens and a concave lens?
The difference is that when virtual image is formed by the concave mirror...it is larger than its original size..but when it is formed by the convex mirror..it is smaller than the original size....
Explain the difference between the concave mirror and convex mirror?
A convex mirror bulges out. A concave mirror curves inward.For a convex mirror, light rays are reflected to meet at a point, while, for a concave mirror, light rays seem to be reflected from a point. If the incident rays were paraxial, the reflected rays are reflected to meet at, or appear to be reflected to a point referred to as the focal point of the lens. For a convex mirror, the focal point is real, while, that of a concave lens is virtual.
