Chapter 6 - Electronic Structure of Atoms - Exercises: 6.27b


- The photon of wavelength $3.3\mu m$ belongs to the infrared region. - The photon of wavelength $0.154nm$ belongs to the X rays region.

Work Step by Step

This question only requires you to look up the electromagnetic spectrum to figure out the region to which each photon belongs. Since we already have the wavelength of each photon, we would see where each photon belongs by matching its wavelength with the wavelength ranges to find out where it fits. - $\lambda_{p1} = 3.3\times10^{-6}m$. This photon would belong to the infrared region, whose wavelengths range from $7.5\times10^{-7}m (750nm)$ to over $10^{-4}m$. - $\lambda_{p2}= 1.54\times10^{-10}m$. This photon would belong to the X rays region, whose wavelengths range from $10^{-11}m$ to $10^{-8}m$.
