O What kind of image do you see using a convex mirror?
A convex mirror will produce an upright, virtual, and diminished image of objects placed in front of it. The image will appear smaller than the actual object, making it useful for security purposes and in vehicles to provide a wider field of view.
Which optical instrument uses a large concave mirror a plane mirror and a convex lens to gather light focus and enlarge an image?
Astronomical telescopes use a large concave mirror, a plane mirror, and a convex lens in their design. The concave mirror gathers light, the plane mirror reflects it to a more convenient viewing location, and the convex lens magnifies and focuses the image for observation.
A mirror or lens that curves outward is?
convex
Who invented the convex mirror?
John J. Convex
Does a convex mirror always produce a virtual image?
yes it always produces a virtual image. it is always erect. Its size is always diminshed. Distance from the mirror is always between Focus and Pole
What is meant by 'principal focus' in a convex mirror?
The principal focus of a convex mirror is the point where incident light rays parallel to the mirror's axis converge upon reflection. It is located behind the mirror and is used to define the focal length and to determine the image formation properties of the mirror.
Why does a convex mirror has a virtual principal focus?
A convex mirror has a virtual principal focus because the reflective surface curves outward, causing the light rays to diverge. When these diverging rays are traced back, they appear to converge at a point behind the mirror, creating the virtual image of the focus.
How do you find the virtual focus in a convex mirror?
since the convex mirror is curved outwards the the focus is 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.
Why can the image formed by a convex mirror not be projected on a screen?
The image formed by a convex mirror is virtual, meaning it appears to be located behind the mirror. Since the rays of light do not actually converge at a real point, they cannot be projected onto a screen. The image in a convex mirror is always smaller than the actual object and can never be brought to a focus.
Which spherical mirror has a virtual focus-concave or convex?
A concave mirror has a virtual focus. This is because the rays of light that are incident on a concave mirror are reflected and appear to diverge from a point behind the mirror, creating a virtual focus.
Does Other name of convex mirror diverging mirror?
Yes, a convex mirror is also known as a diverging mirror because it diverges light rays that fall on it, causing them to spread out. This type of mirror forms virtual, upright, and smaller images of objects placed in front of it.
Why can't a convex mirror create a real image?
Because the focal point of the convex mirror will always be at a 'virtual' place. Convex mirrors focus the image at a definite point.
Why convex mirror has virtual focus?
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.
What is the center of spherical mirror?
The geometric centre of a spherical mirror is called its pole. The centre of the hollow sphere for which the mirror is a part, is called the centre of curvature. The line joining the centre of curvature and the pole is the principal axis. A light ray incident on a spherical mirror, after reflection appears to pass through the principal focus in the case of a convex mirror and passes through the focus in the case of concave mirror. The diameter of the spherical mirror gives the measure of its aperture
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.
What happens when a light ray passes through a focal point and then passes through a covex mirror?
When a light ray passes through a focal point of a convex mirror, it will reflect parallel to the principal axis. This is because the reflected ray follows the law of reflection, where the incident angle is equal to the reflection angle.
