A monochromatic infrared range finder of power 1milli watt emits photons with wavelength 1000 nm in 0.1 second. The number of photons emitted in 0.1 second is:
(Given: h = $6.626 \times 10^{-34} J~s$ , c = $3 \times 10^8 m~s^{-1},$ Avogadro number = $6.022 \times 10^{23}$)

1. $30 \times 10^{37}$
2. $5 \times 10^{14}$
3. $30 \times 10^{34}$
4. $5 \times 10^{11}$

Match types of wave in Column-I with the corresponding frequency in Column-II and mark the appropriate option:
