If the New Horizons space probe transmits to Earth at a frequency of 8.3GHz. At some point the intensity of the wave was I = 2.85e-25 W/m2.

a)     What will be the intensity of the wave three times the distance from the space probe?

b)    What is the wavelength of the transmitted signal?

c)     If the sun power is 3.88e26 W, at what distance form the sun, the radiation intensity will be 0.263 W/m2?

d)    What will be the absorption radiation pressure exerted by the sun on the probe at that distance?

e)     If we consider the above distance as the New Horizons distance to earth. And that the power of the antenna is 17 W. What will be the intensity of the wave transmitted by New Horizons that reaches the earth?
