Answer:
The speed of the wave at the given wavelength and frequency is 60 m/s.
The given parameters;
wavelength of the wave, λ = 0.5 m
frequency of the wave, f = 120 Hz
The speed of the wave is calculated by applying general wave equation as shown below;
v = fλ
where;
v is the speed of the wave
v = 120 x 0.5
v = 60 m/s
Thus, the speed of the wave at the given wavelength and frequency is 60 m/s.
The compound could be Silver Chloride (AgCl).
<h3>What is Silver Chloride?</h3>
Silver chloride is commonly known to be a chemical compound denoted with a chemical formula (AgCl). It is a white crystalline solid and it has low solubility in water.
Due to its sparing solubility in water, AgCl can be separated from other compound mixtures by using a separating technique known as FIltration.
