Two waves, each of frequency 250 Hz and wavelength 25.12 cm, produce
interference in which the maximum amplitude is 0.10 m and minimum amplitude is
0.04 m. Estimate (a) the angular frequency of each wave, (b) the propagation
constant (k) of each wave, (c) the amplitude of each wave and (d) resultant
intensity, if the phase difference between the waves is 3.14 radian.
