High frequency (short wave diathermy) wavelength of 22 meters is:

Explanation:
Wavelength and frequency of electromagnetic waves are inversely related, so you use f = c/λ. With λ = 22 m and the speed of light c ≈ 3.0×10^8 m/s, f ≈ (3.0×10^8) / 22 ≈ 1.36×10^7 Hz, about 13.6 MHz. That matches the standard short‑wave diathermy frequency of 13.56 MHz, which is why this option is correct. The other choices would correspond to shorter wavelengths (27.12 MHz gives roughly 11.1 m, 40 MHz about 7.5 m), so they don’t fit a 22-meter wavelength.
