2021 Answer Seek 5.1 Std Chemistry Draw a wave and explain how a wavelength is measured: Explain frequency: Write down how you would explain the Electromagnetic Wave Relationship to a friend that has a test on it the next day: List the different regions in the Electromagnetic Spectrum in order of least energy to most energy: Describe what Planck explains in his theory (including his constant, a quanta, energy, and photons): 1. The yellow light given off by a sodium vapor lamp used for public lighting has a wavelength of 589 nm. What is the frequency of this radiation? 2. A certain microwave has a wavelength of 0.032 meters. Calculate the frequency of this microwave. 3. A radio station broadcasts at a frequency of 590 KHz. What is the wavelength of the radio waves? 4. A radio station broadcasts music at the frequency of 95.5 megahertz. How much energy is contained in this electromagnetic radiation? 5. Microwave ovens emit microwave energy with a wavelength of 12.9 cm. What is the energy of exactly one photon of this microwave radiation? 6. Calculate the energy of one photon of yellow light that has a wavelength of 589nm.
