Light of wavelength 650 nm and power 2 mW is incident on a semiconductor photodiode with an absorbing layer of thickness 2.65 μm. Assume that 1 % of power is lost on reflection at the surface and the absorption coefficient at this wavelength is 10 cm. What will be the absorbed power? (a) 160 W (b) 198 W (c) 145 W (d) 184 W A system having Lagrangian Le "(을까?-?). The motion represented by the system is: (a) Free particle (b) Oscillatory motion (c) Damped oscillation (d) Simple harmonic motion
