Question 141

Multiple Choice

Electromagnetic radiation with a wavelength of 471 nm appears as blue light to the human eye. The energy of one photon of this light is 4.22 × Electromagnetic radiation with a wavelength of 471 nm appears as blue light to the human eye. The energy of one photon of this light is 4.22 × J. Thus, a laser that emits of energy in a pulse of light at this wavelength produces ________ photons in each pulse. A) 1.5 × B) 1.2 × 10<sup>-23</sup> C) 3.2 × D) 3.1 × E) 6.5 × J. Thus, a laser that emits Electromagnetic radiation with a wavelength of 471 nm appears as blue light to the human eye. The energy of one photon of this light is 4.22 × J. Thus, a laser that emits of energy in a pulse of light at this wavelength produces ________ photons in each pulse. A) 1.5 × B) 1.2 × 10<sup>-23</sup> C) 3.2 × D) 3.1 × E) 6.5 × of energy in a pulse of light at this wavelength produces ________ photons in each pulse.
