Electromagnetic waves, which include light, consist of vibrations of electric and magnetic fields, and they all travel at the speed of light, 3.00×108 m/s Part A: Sunburn (and skin cancer) is caused by ultraviolet light waves having a frequency of around 1.02×10^16 Hz. What is their wavelength? Part B: It has been suggested that extraterrestrial civilizations (if they exist) might try to communicate by using electromagnetic waves having the same frequency as that given off by the spin flip of the electron in hydrogen, which is 1.43 GHz. To what wavelength should we tune our telescopes in order to search for such signals? Part C: Microwave ovens cook food with electromagnetic waves of frequency around 2.45 GHz. What wavelength do these waves have?
