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.
How do you decrease the size of a circle?
Decrease The Length of The Radius
How do you decrease he size of a circle?
By reducing its radius or diameter.
What is the number of cubes a 3-d object can hold?
That depends: * On the size of the 3D object * On the size of the cubes
What is a decrease in size of all dimensions?
A decrease in size of all dimensions refers to a uniform reduction in the length, width, and height of an object or shape. This process is often described as scaling down or shrinking and can result in a smaller version of the original while maintaining its proportions. For example, if a cube is scaled down by half, each side will be half its original length, resulting in a cube that is one-eighth the volume of the original. Such changes can occur in various contexts, including geometric transformations and physical object resizing.
