Physics
Problem
Two interfering waves have the same wavelength, frequency, and amplitude. They are traveling in the same direction but are 90 degrees out of phase. Compared to the individual waves, what can be said about the resultant wave?
a) It will have the same amplitude and velocity, but a different wavelength.
b) It will have the same amplitude and wavelength, but a different velocity.
c) It will have the same wavelength and velocity, but a different amplitude.
d) It will have the same amplitude and frequency, but a different velocity.
e) It will have the same frequency and velocity, but a different wavelength.
