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.
Why is the focal points of a convex lens is real and concave is virtual?
The convex mirror diverges light rays, so if you draw the reflected rays in front of the mirror and continue drawing them at the back of the mirror the virtual light rays (at the back of the mirror) will join. This point is called a Virtual Focus Point.
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 focal point of convex mirror?
The focal point of a convex mirror is located behind the mirror, which means it is a virtual focal point. Light rays that are parallel to the mirror's principal axis will appear to diverge from the virtual focal point after reflection.
Is convex lens a virtual image?
No, a convex lens produces a real image when the object is beyond the focal point and a virtual image when it is closer than the focal point.
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 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.
What is focal point of convex mirror?
The focal point of a convex mirror is located behind the mirror, which means it is a virtual focal point. Light rays that are parallel to the mirror's principal axis will appear to diverge from the virtual focal point after reflection.
Is convex lens a virtual image?
No, a convex lens produces a real image when the object is beyond the focal point and a virtual image when it is closer than the focal 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.
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 creates an image that is reflected through a focal point?
An image that is reflected through a focal point is created by parallel light rays that hit the concave mirror and reflect towards the focal point due to the mirror's curvature. This creates a real, inverted image at the focal point.
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.
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.
