What is above the focus?
Above the focus of a concave mirror, the image is formed. This image can be real or virtual, depending on the position of the object. If the object is placed beyond the focal point, the image will be real, inverted, and reduced in size. If the object is placed between the focal point and the mirror, the image will be virtual, upright, and magnified.
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.
What uses mirrors to focus light from the object being viewed a refracting telescope or a reflecting telescope?
A reflecting telescope uses a curved mirror to concentrate the light from distant stars, and is a very useful technique. There are very clever techniques and technicians, which can produce a mirror perfect over all its area, to within part of the wavelength of light!! The alternative method of using a glass lens, suffers from various difficulties, such as distortion and loss of light. You do not ordinarily consider focus in an astronomical telescope, for all the stellar objects are essentially at infinity.
What is a reflecting telescope that used a secondary mirror to send light through a hole in the primary mirror is called?
It is called a Cassegrain. The small convex subreflector is a hyperboloid with one focus at the focus of the main mirror, and the other focus just behind the main mirror where the eyepiece is.
What is a flat mirror called?
If the mirror is convex (bulges out, like a ball), objects in the mirror will appear smaller or further away, but the mirror will show a larger scene (called a wider field of view), including objects that a flat mirror would miss around the edges. If the mirror is concave (like the inside of a dish), it can magnify images or focus light onto a small spot. A large concave mirror can focus sunlight and produce a very hot spot.
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.
When a small object is placed on the principal axis of a concave mirror between the focus and the mirror?
When a small object is placed on the principal axis of a concave mirror between the focus and the mirror, a virtual and upright image is formed behind the mirror. The image is magnified and located further away from the mirror than the object.
Can the image in a concave mirror be larger than the object?
Yes, the image in a concave mirror can be larger than the object if the object is placed between the focus and the mirror. This creates a virtual, magnified image.
Will an object inside a principal focus be smaller?
No, for a concave mirror the object will become larger. it is virtual the right way up and it is behind the mirror
What is the nature of the image formed by a concave mirror if the object is placed between focus and pole?
The image formed by a concave mirror when the object is placed between the focus and pole is virtual, upright, and magnified. This image appears on the same side as the object.
Which describes how to generate a real image of an object using a concaved mirror?
To generate a real image of an object using a concave mirror, place the object beyond the focal point of the mirror. Light rays from the object will converge after reflecting off the mirror, forming a real and inverted image. Adjust the distance between the object and the mirror to focus the image.
Which describes how to generate a real image of an object using a concave mirror?
To generate a real image of an object using a concave mirror, place the object farther from the mirror than its focal point. The real image will be formed on the same side of the mirror as the object, and it will be inverted and magnified. Adjust the distance between the object and the mirror to focus the image at the desired location.
What is the type of light source that reflects light rays for a microscope?
The type of light source that reflects light rays for a microscope is typically a mirror or a prism. These components are used to direct and focus light onto the specimen being viewed through the microscope.
How do the lenses in a microscope magnify an object?
Lenses in a microscope use refraction to bend light rays and focus them to form an enlarged image of the object being viewed. This magnified image is then viewed through the eyepiece of the microscope, allowing for detailed observation at a much larger scale than with the naked eye.
What does a microscope do to an object?
A microscope magnifies an object, allowing small details to be seen more clearly. It uses lenses to focus light on the object, enabling observers to view it at a level of detail not possible with the naked eye.
Where will the image form when you place an object on the principal axis of a concave mirror at a point between focus and centre of curvature?
If the object is placed on the principal axis of a concave mirror at a point between the focus and centre of curvature the image will form beyond the centre of curvature
What are the properties of images that a concave mirror can produce?
there is an imaginary point in front of the concave mirror, called the focal point or focus, which is half the length of the radius of the sphere of which the mirror was a part of(radius of curvature). usually an object if seen in between the mirror and focus gets magnified, beyond the focus, it gets inverted and reduced.
