with an antenna

4B) Calculate the wavelength of the radiation associated with this signal.

Questions 5) X-rays produced in a diagnostic imaging machine have a wavelength of 8.8 nm. Determine the frequency
of this radiation.

Question 6) Diamondbacks are most sensitive to infrared radiation with a wavelength of 10 mm.

6a) Calculate the frequency of this radiation.

6b) Speculate why snakes have evolved to be sensitive to this frequency of infrared radiation.
