Unformatted text preview: Wave nature of light (c= λν ) Electromagnetic spectrum Photon energy E = h ν Warm-up Problems ------------------------------------------------------------------------------------------- 1: A particular microwave photon has a wavelength of 0.01 m, a photon of green visible light has a wavelength of 520 nm and a photon of gamma radiation has a wavelength of 8 pm. Rank these forms of electromagnetic radiation in order of increasing energy and frequency. Frequency ( ν ): Energy (E): What general trend do we see? 1 Which one of the following photons is higher in energy than a green photon? A. Microwave photon B. ultra-violet photon C. Red photon D. Radio frequency photon -------------------------------------------------------------------------------------------...
