What kind of wavelength do television signals have?
a. short
c. long
b. intermediate
d. very rapid

Television signals have long wavelengths.

Explanation:

Television wavelengths are required to be transmitted over long distances. This is only possible when the wavelength of theses signals is long.

If wavelength of signals is short then there will be difficulty in broadcasting of channels or programs.  

Thus, we can conclude that television signals have long wavelengths.

the positions which points up in upward carbon and down in downward carbon are axial

and vice versa holds true for equatorial positions

so the correct answer with labelled diagram will be
