Voyager 1 space probe transmits to Earth at a frequency of 6.2 GHz. At some point the intensity of the wave was I = 2.95e-25 W / m2.
a) What will be the intensity of the wave at half the distance from the space probe?

b) What is the wavelength of the transmitted signal?

If the power of the sun is 3.87e + 26 W.

c) At what distance from the sun, the radiation intensity will be 0.393 W / m2?

e) If we consider the previous distance as the Voyager 1 distance to the earth. And that the power of the antenna is 18 W. What will be the intensity of the wave transmitted by Voyager 1 that reaches the earth?

f) How many times farther is the Voyager 1 probe from the beginning of the problem?

Need a,b,c,d,e and f. Thanks!

Is this complete question ????

Intensity at what point is 2.95e-25 ??

anyway. intensity varies as

I = 1/r²

______________________________________________

What is the wavelength of the transmitted signal?

wavelength = speed of light / frequency

wavelength = 3e8 / 6.2e9

wavelength = 0.04838 m

__________________________________

At what distance from the sun, the radiation intensity will be 0.393 W / m2

assuming the sun is an isotropic source ( which it is )

I = power / area

area = power / intensity

4r² = power / intensity

4r² = 3.87e26 / 0.393

solve for r, we get

r = 8.852e12 meters ( mind the units , please !!!)

______________________________________________

If we consider the previous distance as the Voyager 1 distance to the earth. And that the power of the antenna is 18 W. What will be the intensity of the wave transmitted by Voyager 1 that reaches the earth

Here antenna is not treated as isotropic source because I think it is always pointed towards earth

Intensity = 18 / pi * 8.852e12²

Intensity = 7.312e-26 W/m²

Space Probe #1 passes very close to Earth at a time that both we (on Earth) and the onboard computer on Probe 1 decide to call t = 0 in our respective frames. The probe moves at a constant speed of 0.5c away from Earth. When the clock aboard Probe 1 reads t = 60 sec, it sends a light signal straight back to Earth. a) At what time was the signal sent, according to the earth’s rest frame? b)...

1.The space probe Voyager 2 flew past Neptune in 1989 at a speed of 38,000 miles/hr. Then, fuel almost entirely depleted, it headed out of the Solar System towards the emptiness of interstellar space (no gravity or friction). It is still trillions of miles away from the nearest star. Will Voyager 2 ever stop, and in any case, what will happen to it in, let's say, the next few weeks? Explain. 2.The present understanding is that the magnetism of the...
