Q59 neet_2024_05_may_morning Photoelectric Effect and Photons
A bulb is rated at 150 watt, converting 8% energy into light. If energy of one photon is 4.42 × 10⁻¹⁹ J, how many photons are emitted by the bulb per second?
  • A. (1) 1.35 × 10¹⁹
  • B. (2) 4.06 × 10¹⁹
  • C. (3) 2.71 × 10¹⁹
  • D. (4) 27.2 × 10¹⁹

Solution

Related Formula
Puseful = P × efficiency N = ElightEphoton
Core Logic
Etotal = 150 J/s Elight = 150 × (8)/(100) = 12 J/s N = 124.42 × 10⁻¹⁹ = 2.715 × 10¹⁹ photons/s
Step 1: Final Selection

Number of photons emitted per second is 2.71 × 10¹⁹.

Pattern Recognition

Always calculate effective power in Joules per second before dividing by single photon energy.
