it is important so you can discover new materials or inhabitle planets in case anything happens to earth
Answer:
In constructive interference, a crest meets a crest or a trough meets a trough, resulting in a larger crest or trough.
In destructive interference, a crest meets a trough and results in cancellation hence a smaller disturbance than either of the two interacting waves.
Answer:
Wavelength,
Explanation:
It is given that,
Speed of radio waves is
Frequency of radio waves is f = 101,700,000 Hz
We need to find the wavelength of WFNX’s radio waves. The relation between wavelength, frequency and speed of a wave is given by :
is wavelength
So, the wavelength of WFNX’s radio waves is 2.94 m.
