A weakly guiding fibre with a particular graded core index has cut-off V-values for its 2nd, 3rd and 4th modes of 2.5, 3.9 and 5.2, respectively. The core radius is 4 microns, the core index is 1.47 and the cladding index is 1.46.
Determine the range of source wavelength values in nm for which the fibre is:
(a) single-mode
(b) two-mode,
(c) three-mode
(d) more than 3-mode.
What are end-terminations? Again, we get ourselves in an area where many confusion and controversy are the order of the day. Several American institutions have tried to set sta

Suppose you sound a 1056-Hz tuning fork at the same time you strike a note on the piano and hear 2 beats/second. You tighten the piano string very slightly and now hear 3 beats/s
Ascooter acquires velocity of 36km/hr in 10 secs just after the start and stops after 20 secs. Find the acceleration in both cases.
1. A given radioactive sample emits only one type of radiation. When placed in a counter for 10 minutes, 1632 counts are registered. Then the sample is removed and a background
