Answer:
11m
Explanation:
Wavelength of a wave is the distance between successive crests and trough of a wave. It is represented mathematically as the ratio of the speed of the wave to its frequency. It can be expressed as;
Wavelength ¶ = wave speed (v) /frequency (f)
Given the speed of light c = 2.9979 10^8 m/s.
frequency of the radio wave = 27.075 MHz = 27.075×10^6Hz
Wavelength = 2.9979 10^8/27.075×10^6
Wavelength = 0.11×10^2
Wavelength = 11m
Therefore, the wavelength of the electromagnetic wave being used is 11m
Answer: Their final relative velocity is -0.412 m/s.
Explanation:
According to the law of conservation,
Putting the given values into the above formula as follows.
v = 
= -0.412 m/s
Thus, we can conclude that their final relative velocity is -0.412 m/s.
