Division of Periodic Table into s-, p-, d- and f blocks on the Basis of Electronic Configurations. The long form of periodic table can be divided into four main blocks. These are s-, p-, d- and f-blocks. The division of elements into blocks is primarily based upon their electronic configuration as shown in Fig. 6.2.
What is it? The EquiCam is the ultimate piece of filming equipment for equestrian sports, a miniature super light weight camera (just 38g) and two special riding hat camera mounts (elastic hat strap and a hat mount). Film your rides in full 1080p HD for fun and for safety.
The lenses that have the built-in focusing motor have the designation AF-S, which stands for Auto Focus-Silent Wave Motor. Lenses that do not have this built-in motor cannot autofocus on the D3300 and D5300 camera bodies. Many, but not all, of the Nikon lenses have a switch on the camera barrel that allows you to switch between manual focus and autofocus. This switch is labeled with M/A and M. In the M/A mode, the camera tries to autofocus as long as the camera is set to autofocus.
