A chicken taco salad without dressing at one Mexican restaurant chain contains a whopping 1,180 calories. In addition, it provides 75 grams of fat, 79 grams of carbohydrate, 52 grams of protein, 13 grams of fiber, and 2,160 mg of sodium.
Infrared Light. Infrared (IR) light is light with lower frequency (higher wavelength) than visible light. IR light has frequencies ranging from 3*1011 to 4*1014 Hz (300 GHz to 400 THz) and wavelengths from 7.5*10-7 m to 10-3 m (750 nm to 1 mm).
Frequencies below 15 Mhz or so, are rarely used due to absorption of these waves by the ionosphere. At the upper end of the frequency range, limitations are imposed by the technology needed to receive signals with such tiny wavelengths. Almost all amateur radio telescopes fall between 18 Mhz and 10,000 Mhz.
