LASIK eye surgery uses pulses of laser light to shave off tissue from the cornea, reshaping it. A typical LASIK laser emits a 1.0-mm-diameter laser beam with a wavelength of 193 nm. Each laser pulse lasts 15 ns and contains 1.0 mJ of light energy.a. What is the power of one laser pulse?b. During the very brief time of the pulse, what is the intensity of the light wave?
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?
