A 1kW radio transmitter operates at a frequency of 880 kHz. How many quanta per second does it emit?
Correct answer: B. B) 1.71x10³⁰
- A. A) 1.71x10²¹
- B. B) 1.71x10³⁰
- C. C) 6.02x10²³
- D. D) 2.85x10²⁶
Explanation
First, find the energy of a single quantum (photon) using E = hf. Then, divide the total power of the transmitter (1000 J/s). by the energy per quantum to find the number of quanta emitted per second. The result is approximately 1.71 x 10³⁰.
