4.64 × 10⁻²¹ J/s
Explanation:
[Only if the wave travels at the speed of light]
Because a wave presumed to be at light speed is a photon, E = hf.
If frequency is not given, E = hc/λ
c is the speed of light in meters per second. c = 299, 792, 458 m/s.
λ is the wavelength which is dependent.
h or plancks constant = 6.62607004 × 10⁻³² m² kg / s.
E is in units of J / s or jules ( m² kg ) per second.
If the wave has a frequency of 7.0 x 10¹² Hz or 7 THz (Tera-Hertz).
E = (6.62607004 × 10⁻³⁴) × (7.0 × 10¹²) =
46.38249028 × 10⁻²² =
4.638249028 × 10⁻²¹ J/s ≈
4.64 × 10⁻²¹ J/s
