Consider the water wave shown here.
(a) How could you measure the speed of this wave?
(b) How would you determine the wavelength of the wave?
(c) Given the speed and wavelength of the wave, how could you determine the frequency of the wave?
(d) Suggest an independent experiment to determine the frequency of the wave.
A student analyzed and recorded two potassium emission spectra: 1) one using 0.10 M Potassium sulfate solution; 2) one using 0.10M Potassium nitrate solution;. Determine why will significant differences be observed in the two emission spectra.
