Dependent on the location of an object in front of the concave mirror, the image can be real or imaginary. If the object is closer to the mirror than the focal length, the image is imaginary and upright. If the object is further from the focal length, the image is real and ...
The concave mirror is a type of converging mirror which converges the rays coming towards it onto the focus of the mirror and generally forms the real and inverted image of the object and for the special case when the object is placed at the f...
Two object A and B when placed in turns infront of a concave mirror, give images of equal size. The focal length of the concave mirror is 7.5cm and size of object A is three times the size of object B from the mirror , if A is placed 30cm from the mirror. A18cm B15cm C20cm...
To determine which mirror is used as a shaving mirror, we can follow these steps:1. Identify the Type of Mirrors: - There are different types of mirrors: concave, convex, and plane mirrors. Each has unique properties.
2. How can a plane mirror, concave mirror, convex mirror, converging lens and/or diverging lens be used to produce a magnified image? Plane mirrors, convex mirrors,and diverging lenses will never do this. ... Plane mirrors, convex mirrors, and diverging lenses will always produce an upright...
(III) An object is placed a distance r in front of a wall, where r exactly equals the radius of curvature of a certain concave mirror. At what distance from the wall should this mirror be placed so that a real image of the object is formed on the wall...
(a) If the sign of f is positive, the lens will be convex and if it is negative, the lens will be concave. (b) If v is positive, the image will be virtual and erect. Again if v is negative, the image will be real and inverted. ...
A Cassegrain telescope is a wide-angle reflecting telescope with a concave mirror that receives light and focuses an image. A second mirror reflects the light through a gap in the primary mirror, allowing the eyepiece or camera to be mounted at the back end of the tube. The Cassegrain reflec...
An erect object is located between a concave mirror and its focal point. Its image is:A.real, erect, and larger than the objectB.virtual, erect, and larger than the objectC.real, inverted, and larger than the objectD.virtual,inverted, and larger than the
And the image is inverted. So it’s not a point and shoot spyglass. [For that, you would want a Refractor or Hybrid.] But take the NexStar 130 out on star-date night and your view will be truly stellar. With a 130mm (5inches) of beefy main mirror, we didn’t expect this unit...
