Practicing Success
A monochromatic source emitting light of wavelength 300 nm has a power output of 33 W. Calculate the number of protons emitted by this source in 2 minutes. $(h=6.62×10^{-34}Js)$ |
$6×10^{21}$ $4.2×10^{20}$ $3.8×10^{24}$ $1.6×10^{19}$ |
$6×10^{21}$ |
The correct answer is Option (1) → $6×10^{21}$ |
