Abstract

Generation and detection of second sound have been extended to 25 Mc/sec using a resonant cavity technique. Investigations show the attenuation coefficient of second sound is proportional to the square of the frequency up to 1.3 Mc/sec at 1.22°K, 4 Mc/sec at 1.47°K, and 10 Mc/sec at 1.9°K - 2.1°K in agreement with Khalatnikov's theoretical predictions and with previous low frequency measurements.
