Why concave mirror is used for shaving?
Some people use concave mirror because when a man stands between the principal focus and pole of a concave mirror,he sees an enlarged,erect and virtual image of his face.this is the reason why a concave mirror of large focal length is used for shaving. concave mirrors concentrate on one focus and while shaving it concentrate on a point and the image is enlarge which prevents the face from cutting. because when a man stands between the pricipal focus and pole of a concave mirror , he sees enlarged ,erect and virtual image of his face .that is why concave mirror of large focal length is used for shaving
What part of a reflecting telescope form the image?
a concave mirror and an angled plane mirror
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.
What does negative magnification mean?
Negative magnification typically occurs when the image produced by an optical system appears inverted relative to the object being viewed. This happens when the image is smaller than the object, indicating that the image is reduced in size relative to the object. Negative magnification is common in situations where a concave lens or diverging mirror is used.
List 5 properties of a virtual image creaed by reflection from a plane mirror?
1. Image is upright 2. Image is virtual 3. Image is of same size as object 4. Image is laterally inverted 5. Distance from object to mirror is equal to the distance from the mirror to the image
Who Describe the images produced by a plane mirror a concave mirror and convex mirror?
A plane mirror produces an upright and laterally inverted image that is the same size as the object. A concave mirror produces a real or virtual, inverted or upright image that can be larger or smaller than the object depending on the object's position relative to the mirror. A convex mirror produces a virtual, upright, and smaller image compared to the object, regardless of the object's position relative to the mirror.
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.
Why concave mirror is used for make up pr shave?
A concave mirror is used for makeup mirrors/shaving mirrors because it produces an image that is larger than the object.
Which mirror produces an erect diminished virtual image?
A concave mirror when the object is placed between the focal point and the mirror will produce an erect, diminished, and virtual image. This type of mirror is commonly used in makeup mirrors and shaving mirrors.
How would the eye perceive an image created by a concave mirror and by a convex mirror?
The image formed by a concave mirror can be real or virtual, depending on the object's position relative to the mirror. A real image is formed in front of the mirror and can be projected onto a screen, while a virtual image is formed behind the mirror and cannot be projected. Conversely, a convex mirror always produces a virtual, upright, smaller image of the object. The image appears closer to the mirror than the actual object and does not form a focused point.
What does the image of an object look like for a concave mirror when the object is far away?
When the object is far away from a concave mirror, the image formed is real, inverted, and highly magnified. This image is formed at the focal point of the mirror.
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.
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 type of mirror would you use to view an enlarged image of an object?
You would use a concave mirror to view an enlarged image of an object. Concave mirrors can focus light rays to create a magnified image that appears larger than the actual object.
What type of mirror is used whenever a magnified image of an object is used?
A concave mirror is typically used to create a magnified image of an object. The mirror curves inward and can produce an enlarged virtual image when the object is placed within the focal length of the mirror.
What happens when you hold an object far away from a concave mirror?
When you hold an object far away from a concave mirror, the mirror will produce a real image that is inverted and smaller than the object. The image will be formed at the mirror's focal point.
A concave mirror can form a real image which is a copy of an object that forms?
Yes, a concave mirror can form a real image that is inverted and smaller than the object. This type of image is produced when the object is placed beyond the mirror's focal point.
