The graph shows the intensity of direct radiation in W/m² throughout the day. It is the amount of power that would be received by a tracking concentrator in the absence of cloud. The time is the local solar time. Set the latitude to your location and then adjust the day

Most of the energy carried by high-intensity ultrasound in tissue is converted to thermal energy. In fact, intensities of 10 3 to 10 4 W/m 2 are commonly used for deep-heat treatments called ultrasound diathermy. Frequencies of 0.8 to 1 MHz are typical.
