Answer:
The correct option is (c) "periodic wave"
Explanation:
The relationship between the angular frequency and the radial frequency is :
[tex]\omega=2\pi f[/tex]
f is the radial frequency
Frequency, wavelength, velocity of propagation, and related variables do not depend on the amplitude of wave. Travelling waves are also known as periodic wave if their waveform repeats every time interval T. Frequency, wavelength and the speed of wave are the factors that defines traveling waves.
So, the correct option is (c) "periodic wave".
