What are the characteristics of a concave mirror?
A concave mirror is a converging mirror used in microscopes and telescopes. Characteristics include forming real and inverted and diminished images when an object is placed beyond the center of curvature or real, inverted and enlarged image when the object is placed between the center of curvature and focus.
What mirror causes light rays to converge?
concave mirror and convex lens can be used to focus light rays. they are also called converging mirror and lens respectively. They focus the light at a distance of its focal length.
Can a converging lens have more than one focus?
can a converging lens have more than one focus
Describe the Images produced by a concave mirror?
A concave mirror, or converging mirror, has a reflecting surface that bulges inward (away from the incident light). Concave mirrors reflect light inward to one focal point.They are used to focus light. Unlike convex mirrors, concave mirrors show different image types depending on the distance between the object and the mirror.These mirrors are called "converging" because they tend to collect light that falls on them, refocusing parallel incoming rays toward a focus. This is because the light is reflected at different angles, since the normal to the surface differs with each spot on the mirror.
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
Does light reflected off of a mirror increase the foot candles?
Of sorts, it reflects and focuses it into a single path, instead of it just going anywhere it desires.IN ADDITION:No. The reason for this is that the mirror blocks the light that it reflects. One side of the candle is twice as bright because of the mirror, but one side isn't lit at all. So the same amount of light, just directed differently. A convex mirror does focus the light from a candle into a tighter beam.
What is the different between concave and convex mirror light?
Concave mirror would have the surface curved out get coated with mercury hence curved in surface would reflect the rays fallen on. But convex mirror would have the surface curved in get coated with mercury hence curved out surface would reflect the rays fallen on. Concave mirror would have both converging and diverging ability. When light coming from an object placed at a distance higher than its focal length right from the pole of the mirror, converging takes place. But the object lies in between pole and the focus diverging action. But in convex mirror irrespective of the placement of the object only diverging phenomenon. Concave mirror used as shaving mirror and dentists too use them Convex mirror is used as rear view mirror in case of vehicles near by the driver.
To take a clear picture of an image in a mirror should the camera be focused on the image or the mirror?
An image in a mirror is a "virtual" image which takes on certain characteristics. One of these characteristics is that the apparent distance is equal to the distance from the observer to the mirror plus the distance from the mirror to the subject. If the observer and subject are the same, then the apparent distance is twice that of the subject to the mirror. If the observer is 3 feet from the mirror and the subject is 20 feet away, the apparent distance is 23 feet. If you focus on the subject and have distance markings on your lens, you can prove this to yourself.
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 the function of the convex lens of the eye?
Convex lens- converging lens: lens such that a beam of light passing through it is brought to a point or focus. This type of lens is often used for close examination of samll objects. Examples: manifying glass, small car mirror, 7-eleven mirror
Ford Focus mirror glass?
The mirror glass for a Ford Focus is available online at places like CariD and Parts Geek. You can also buy the entire mirror online on eBay for about $30.
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.
