and the having the shortest ending with radiation wavelength. Give the high and low wavelength values that define the visible region of the electromagnetic spectrum. Briefly explain Planck's quantum theory and explain 7.4 The Ph tum is. What are the units for Planck's Review constant? Give two everyday examples that illustrate the con- cept of quantization. 7.13 er Problems 7 (a) What is the wavelength (in nanometers) of light having a frequency of 8.6 Ã 1013 Hz? (b) What is the frequency (in Hz) of light having a wavelength of 566 nm? (a) What is the frequency of light having a wave- length of 456 nm? (b) What is the wavelength (in nanometers) of radiation having a frequency of 2.45 Ã 109 Hz? (This is the type of radiation used in microwave ovens.) rallel 7.8 deline fir cla- c number table 7.9 The average distance between Mars and Earth is about 1.3 Ã 108 miles. How long would it take TV pictures transmitted from the Viking space vehicle on Mars' surface to reach Earth? (1 mile 1.61 km.)
