A radio transmitter operates at a frequency 880 kHz and a power of 10 kW. The number of photons emitted per second is

1. 1.72 × 10³¹
2. 1.327 × 10²⁵
3. 1.327 × 10³⁷
4. 1.327 × 10⁴⁵

Correct Option: A

No. of photons emitted per sec,

n =	Power
	Energy of photon

=	P	=	10000
	hv		6.6 × 10^-34 × 880 × 10³

= 1.72 × 10³¹
