Practice Problem #1 A sodium vapor lamp emits light photons with a wavelength of 579 nm. What is the energy of these photons? Practice Problem #2 Find the energy for an x-ray photon with a frequency of 2.4 × 1018 Hz. Practice Problem #3 What is the frequency of UV light that has a...
The longest wavelengths of light are red. The shortest wavelengths light are violet. Above red on the spectrum are microwaves followed by Radio waves. Below violet light is ultraviolet, followed by x-rays then gamma rays. Try the electromagnetic spectrum calculation practice problems...

However, there is limited data on the application of PEMF therapy in the areas of the CAI spectrum. Recent evidence has shown that PEMF therapy may improve muscle contraction by increasing muscle activation and reducing electromechanical delay independently from the neural pathway, which resulted in ...
