Question

A local radio station broadcasts at a frequency of 629 kHz. Calculate the energy of the frequency at which it is broadcasting.

a) E = mc²
b) E = hf
c) E = 1/2 mv²
d) E = pV

Answer 1

The energy of the frequency at which the local radio station is broadcasting is approximately 4.16 × 10^-26 Joules.

Step-by-step explanation:

The energy of a photon can be calculated using the equation E = hf, where E represents energy, h represents Planck's constant (6.626 × 10-34 J·s), and f represents frequency.

In this case, the frequency of the radio station is given as 629 kHz, which can be converted to 629 × 103 Hz.

Using the equation, we can calculate the energy:

E = (6.626 × 10-34 J·s)(629 × 103 Hz)

E ≈ 4.16 × 10-26 J

Therefore, the energy of the frequency at which the local radio station is broadcasting is approximately 4.16 × 10-26 Joules.
