In an experiment to measure the focal length of a convex lens, the measured focal length is shorter than the actual value. What could be the cause? A. The object distance is measured inaccurately and is too large. B. The image distance is measured inaccurately and is too small. C. The...
Hint:When a concave lens and a convex lens of the same focal length are in contact, then the power of the lens combination will be zero and its focal length will be infinite. Therefore, the combination behaves as a plane glass plate. Formula used: The effective ...

1. The focal length of the objective of a microscope is less than the focal length of the eyepiece 2. The minimum distance between an object and its real image formed by a convex lens of focal length f is equal to 4 f Which of the statements given above is / are correct ...
Theoretically, the beam waist using a 0.42 NA objective lens is 3.9 × smaller than that using a 0.14 NA objective lens, due to the combination of the different NA and that the beam underfilled the entrance aperture for the 0.14 NA lens (see Table 1). Experimentally, we find a 2 × ...

Consequently, we find that a few LDI layers (i.e., 5) are sufficient to produce a close-to-ground-truth hologram, and thus it is highly data-efficient. Fourth, once the number of layers is set, its feature length is fixed and independent of scene complexity; thus, it is CNN- ...
