Mechanical properties of snow were investigated by means of a vibration response technique in a frequency range from 10 Hz to 1MHz and a temperature range from −15° to −0.1°C with heating and cooling processes. The response signa... I Takei,N Maeno - 《Annals of Glaciology》 被引...
Convert a wavelength of 3.31μm to cm−1. Wavelength: The wavelength depicts the length for a complete cycle of a wave would complete. Now, this would be quite an important parameter of a wave since we would be able to quantify the frequency or the wave speed when we have one other ...
