What else can I help you with?
If the image distance from a len is 5cm and the object distance is 7.5 cm what is the focal length of the lens?
Use the thin lense equation. 1/f = 1/d + 1/o, where f is the focal length, d is the image distance, and o is the object distance.
Which factor most influences the image produced by reflection of an object in a concave mirror?
distance from mirror
What is a virtual image?
In optics, a virtual image is an image in which the outgoing rays from a point on the object never actually intersect at a visable point. However, if these rays were stretched out they would intersect at a point behind the mirror/surface.
An object is located 51 millimeters from a diverging lens the object has a height of 13 millimeters and the image is 3.5 meters how far in front of the lens is the image located?
13.7 millimetersThis answer is correct, but the formula is most important.The formula is:Hi = height of imageHo = height of objectSi = Distance of image from lensSo = Distance of object from lensYou are trying to find Si, so that is your unknown.Here is your formula: Hi/Ho = Si/SoOr in this case: 3.5/13 = Si/51The rest is basic algebra.Good luck!You can use the ratio equation; (Image Height)/(object height) = - (image location)/(object location) In your case you will get a negative location which means the image is on the same side of the lens as the incoming light.
Which factor most influences the image produced by reflection of an object on a concave mirror?
The focal point. It can affect size, real/virtual, inverted/upright.
How does the image distance compare to the object distance?
The image distance is the distance from the lens to where the image is formed, while the object distance is the distance from the lens to the object. In general, for real images, the image distance is different from the object distance. For virtual images, the image distance is negative and the object distance is positive.
Why if you move the object away from the lens the size of the image get smaller?
Moving the object away from the lens increases the object-image distance. According to the thin lens equation, as the object-image distance increases, the image distance increases incrementally more than the object distance. This results in a smaller image size due to the inverse relationship between image size and image distance.
What is the object image distance relationship for a flat mirror?
when dealing with a flat mirror object-distance and image-distance should be equal.
Is the distance from the object to the mirror is less than the apparent from the image?
The distance from the object to the mirror is equal to the distance from the image to the mirror in a plane mirror. The image appears to be as far behind the mirror as the object is in front of it, so the apparent distance from the image to the mirror is equal to the actual distance from the object to the mirror.
What is the difference between object distance and image distance?
image distance is the distance from the point of incidence on the mirror, the where the image is reflected to.object distance is the distance from the actual object being reflected to the point of incidence on the mirror where it's reflected as an image.
How does the distance of the object compare with the distance of the image from the plane mirror?
The distance of the object from the mirror line should equal the distance of the image from the mirror line.
How are focal length object distance and image distance related?
The focal length of a lens is related to the object distance and image distance by the lens equation: 1/f = 1/do + 1/di, where f is the focal length, do is the object distance, and di is the image distance. This equation describes how the lens focuses light rays from an object at a certain distance to form an image at a specific distance.
What is the relationship between image distance and object distance in optics?
In optics, the relationship between image distance and object distance is described by the lens equation: 1/f 1/di 1/do, where f is the focal length of the lens, di is the image distance, and do is the object distance. This equation shows that as the object distance changes, the image distance also changes in a reciprocal manner.
What happens to the image distance as the object distance increases?
As the object distance increases, the image distance also increases. This relationship is governed by the lens or mirror equation, which shows that when the object is moved farther from the lens or mirror, the image is also formed farther from the lens or mirror.
What is the relationship between object distance image distance and focal length of a concave mirror?
In a concave mirror, the relationship between object distance, image distance, and focal length is described by the mirror formula: 1/f = 1/do + 1/di, where f is the focal length, do is the object distance, and di is the image distance. As the object distance changes, the image distance and focal length will also change accordingly.
With a plane mirror what would be the relationship between di the image distance and do the object distance?
In a plane mirror, the image distance (di) is equal to the object distance (do). The image formed is virtual, upright, and the same size as the object, and it appears behind the mirror at the same distance as the object in front of the mirror.
What is the Magnification equation for concave mirror?
The magnification equation for a concave mirror is given by the formula: M = - (image distance) / (object distance), where M is the magnification, image distance is the distance from the mirror to the image, and object distance is the distance from the mirror to the object. Negative magnification indicates an inverted image.
