You can buy them on line, but I buy this brand at the market, which is a bit more expensive on line, although I do not know what shipping costs are. I store the jars in the fridge after I have opened them, and I imagine that you could store tinned anchovies in olive oil in a small jar in the fridge for some time.
Wave Velocity vs Wave Frequency. Wave velocity and wave frequency are two very important properties of a wave. The wave velocity describes how fast the energy is propagating. The wave frequency describes how fast the wave is oscillating. Both of these properties are very important in defining and describing the wave. Wave velocity is a property of the medium for a certain type of wave. The wave frequency is a property determined by the frequency of the source. â¢ Wave frequency stays constant regardless of the medium the wave is travelling on. Wave velocity changes with the medium.
The rate of its motion is 2 cycles/second. This rate is referred to as the wave frequency. Thus the wave frequency shows that how much the medium particles undergo in vibration when a wave is passed through that medium. It is cycles per second or waves per second or vibrations per second.he frequency is the quantity obtained when we divide velocity of the wave by its wavelength. f = $\frac{1}{T}$ where T = time period. The figure depicts the different types of waves as classified according to their frequencies.
