How does the length of the periscope affect the size of the image seen?
The length of the periscope does not affect the size of the image seen. The size of the image is determined by the mirrors inside the periscope that reflect the light, not the length of the periscope itself.
How do you adjust d size of image in photo shop?
Go to Image > Image Size and type numbers or choose Percentage and type percentage in Height or Width fields at top of Image Size window.
Does the image size increase as the image distance increases?
No, the size of the image does not increase as the image distance increases. The size of the image is determined by the object distance, focal length of the lens, and the distance between the lens and the image plane.
Do the aperture controls adjust the length of time the light strikes the sensor?
No, the aperture controls adjust the size of the opening that light enters the camera through (see image above, left maximum aperture setting, right minimum aperture setting).
Does a 100mm lens produce and image that is twice as high and twice as wide as a 50mm lense?
No, the focal length of a lens does not determine the size of the image produced. The size of the image is influenced by factors such as the distance to the subject and the sensor size of the camera. The focal length of a lens primarily affects the field of view and magnification of the image.
What factor determines the location and size of the image produced by converging lens?
The location and size of the image produced by a converging lens are determined by the object distance and the focal length of the lens. The image is formed on the opposite side of the lens as the object when the object is beyond the focal point (real image), and the size of the image depends on the object distance and focal length according to the lens formula.
Where can you download Irfanview for Mac or a photo editting software similar to that where you can manually put it size values to stretch or shrink or expand a picture?
IrfanView is only available for the Windows operating system and will not work with Mac OS X. All image handling software can change the size of an image. The Mac's Preview application (in the Applications folder) can be used to open the image, and from the Tools menu select Adjust Size... to adjust the size of the image. If the image is in the Mac's iPhoto library you can Export from the library (from iPhoto's File menu) and change the size as required. All other image editing software will offer similar size changing options.
How large the image will be if the object is 25cm tall?
The size of the image will depend on the distance between the object and the lens (or mirror) producing the image. If you provide information about this distance, we can help calculate the size of the image.
How does the size of the image compare to the size of the object?
The size of the image is based on the distance between the object and the lens, as well as the focal length of the lens. The image can be the same size as the object if the object is at the focal point and the lens follows the 1/f = 1/do + 1/di equation.
Do the objects size change when its placed at the focal length of the concave mirror?
The objects size is not going to change. The image size, however, would.
The apparent size of an object is determined by the size of its image on?
The apparent size of an object is determined by the size of its image on the retina of the eye. It is influenced by factors such as the distance between the object and the eye, the focal length of the lens or mirror creating the image, and the size of the object itself. The brain processes this information to perceive the object's size.
What is the size of the smallest vertical plane mirror in which a 6 ft tall person standing erect can see her length image?
The size of the mirror needs to be at least half the height of the person standing in front of it in order for the person to see their full length image. Therefore, a 3 ft tall vertical plane mirror would be the smallest size in which a 6 ft tall person can see their full length image.
