Polyethylene is produced by In an optical fiber, the pulse dispersion effect is minimized by 1. Using a high frequency light source 2. Using plastic cladding 3. Minimizing the core diameter Which of the above statements is/are correct? Reciprocity theorem is applicable to Antenna elevation angle at the ground station for satellite communication is always kept above 5° to Consider a silicon sample at T = 300 K, with a uniform donor density N d = 5 × 10 16 cm -3 illuminated uniformly such that the optical generation rate is G opt = 1.5 × 10 20 cm -3 s -1 throughout the sample. The incident radiation is turned off at t = 0. Assume low-level injection to be valid and ignore surface effects. The carrier lifetimes are τ p0 = 0.1 µs and τ n0 = 0.5 µs. The hole concentration at t = 0 and the hole concentration at t = 0.3 µs, respectively, are
