The sign of the focal length for a diverging lens is negative. This indicates that the focal point is located behind the lens where the light rays appear to diverge.

If the image produced by a lens is the same size as the object then the lens must be?

A diverging lens. In this case, the object distance will be equal to the image distance but with opposite sign.


What is the ratio of heigh of object to height of image?

The ratio of the height of an object to the height of its image is equal to the ratio of their distances from the lens or mirror. This relationship is defined by the magnification formula in optics, where M = -di/do (negative sign indicates inverted image). The ratio is dependent on the type of lens or mirror used and the placement of the object relative to the focal point.


What is focal fatty?

"Focal fatty infiltration" refers to the accumulation of fat in a specific area or focal point within an organ, commonly seen in the liver. It is usually a benign condition and does not typically cause symptoms. However, it can sometimes be a sign of underlying liver disease or metabolic abnormalities.


What is the Magnification equation for convex mirror?

The magnification equation for a convex mirror is given by: M = -1 / (1 - d/f), where M is the magnification, d is the object distance, and f is the focal length of the mirror. The negative sign indicates that the image formed is virtual and upright.


What is focal asymmetry in the breast?

Focal asymmetry in the breast refers to an area on a mammogram that appears different in density or shape from the surrounding tissue. It may indicate a potential abnormality that requires further evaluation, such as additional imaging or a biopsy, to determine if it is benign or could be a sign of breast cancer.

WHAT IS THE IMAGE DISTANCE OF AN OBJECT PLACED CM FROM A CONVERGING LEN OF FOCAL LENGTH CM?

To determine the image distance (v) for an object placed at a distance (u) from a converging lens with a focal length (f), you can use the lens formula: ( \frac{1}{f} = \frac{1}{v} - \frac{1}{u} ). If both the object distance and focal length are given in centimeters, substitute those values into the equation to solve for v. Remember that the object distance is negative in the lens formula convention. The resulting image distance will indicate whether the image is real or virtual based on its sign.


A 2cm tall object is placed perpendicular to the principal axis of a convex lens of focal length 10cmThe distance of the object from the lens is 15cm Find the position nature and height of the imag?

An image formed by a convex lens is described by the lens equation 1/u+1/v=1/f, where u is the distance of the object from the lens, v is the mage distance from lens and f is the focal length of the mirror. The question states that f=10cm and u=15cm, This can be substituted in the lens equation as follows: 1/15+1/v=1/10 1/v =1/30 V=+30 Magnification =v/u =30/15=2. The positive sign of v means the image is real, inverted and it on the opposite side of the object. Solution: The image is twice the same size as the object, real, inverted and on the opposite of the object.


Is lens formula valid only for convex lens?

I believe it can be used for any lens. Just be sure to use the correct sign. Check the "lensmaker's equation" in Wikipedia, and the comments about what sign to use.

What does non focal mean?

In the context of optics or photography, "non-focal" typically refers to objects or elements that are not the primary focus of the lens. This can include background elements or out-of-focus areas in an image. Non-focal points do not fall within the plane of focus determined by the lens and may appear blurry or less defined compared to the focal point.


The length of a sign is 4 inches more than the width The area is 45 square inches Identify the length and width of the sign?

9 and 5


If the length of a sign is 4 inches more thqn the width and the area is 45 square inches what is the length and width of the sign?

9" x 5"


Do you have to put the square or cubic sign after inches and centimeters?

You have to put the square sign when you use area and the cubic sign when you use volume. Area= Length times Width Volume= Length times Width times Height
