How much energy does a wave with a frequency of 7.0 x 1012 Hz have

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
