If you detected radio signals with an average wavelength of 67 cm and suspected that they came from a civilization on a distant Earth-like exoplanet, roughly how much of a change in wavelength (in cm) should you expect to detect as a result of the orbital motion of the distant exoplanet?

0.0066553 cm

Explanation:

v = Earth's average orbital velocity = 29.8 km/s

c = Speed of light =

= Wavelength = 67 cm

= Change in wavelength

The Doppler shift is given by

The change in wavelength is 0.0066553 cm

there are no correct statementd on the list of choices you provided.

hi i’m sorry to call us today so we will get back with y’all and we will have to do it haha omg was the day
