Answer;
v = 1.165 × 10^6 m/s
Explanation;
Δf = –v/λ = –vf/s
v = velocity of source relative to listener
λ = wavelength of source, relative to source
f = frequency of source, relative to source
s = speed of wave in medium
C = speed of light = 3 × 10^8 m/s
Δf = vf/s
= 102 - 101.6 = 0.4 MHz = 400 kHz
v = 400 kHz x 3 ×10^8 / 103 000 kHz
v = 1.165 × 10^6 m/s
The velocity of spacecraft will be "1.165 × 10⁶ m/s".
According to the question,
Speed of light, C = 3×10⁸ m/s
Frequency, 102 mhz
101.6 mhz
As we know the relation,
→ [tex]\Delta f = -\frac{v}{\lambda}[/tex]
[tex]= -\frac{vf}{s}[/tex]
then,
→ v = 102 - 101.6
= 0.4 MHz or, 400 kHz
hence,
The velocity will be:
→ v = [tex]400\times \frac{3\times 10^{-8}}{103000}[/tex]
= [tex]1.165\times 10^{6}[/tex] m/s
Thus the above response is appropriate.
