Answer:
λ = 28,14 m
Explanation:
To find the wavelength of the wave you use the following formula:
(1)
v: speed of the wave = 1,97 m/s
λ: wavelength
f: frequency of the wave = 0,07 Hz
You replace the values of v and f in the equation (1) and solve for λ:

hence, the wavelength of the wave is 28,14 m
Basic solutions are hydroxides therefore the answer is A ca(OH)2
