Answer: The velocity is the wave traveling at before the transmitter converts it to a sound wave is [tex]2.99\times 10^8 m/s[/tex]
Explanation:
Wavelength of the electromagnetic wave = 23,076 m
Frequency of the wave = 13,000 Hertz
[tex]\text{Time period}=\frac{1}{Frequency}[/tex]
[tex]Velocity=\frac{displacement}{Time}=\frac{\lambda}{\text{Time period}}=\lambda \times Frequency=23,076\times 13,000 Hertz=2.99\times 10^8 m/s[/tex]
The velocity is the wave traveling at before the transmitter converts it to a sound wave is [tex]2.99\times 10^8 m/s[/tex]
The velocity the wave was traveling at before the transmitter converts it to a sound wave is 3.0 x 10⁸ m/s.
Velocity of waves
The velocity of waves is the rate of change of the wave's displacement with time.
The velocity of waves is determined by taking the product of the wave's frequency and wavelength.
v = fλ
v = 13,000 x 23,076
v = 3.0 x 10⁸ m/s.
Thus, the velocity the wave was traveling at before the transmitter converts it to a sound wave is 3.0 x 10⁸ m/s.
