Ch.6 - Electronic Structure of Atoms
Chapter 6, Problem 100a

The Chemistry and Life box in Section 6.7 described the techniques called NMR and MRI. (a) Instruments for obtaining MRI data are typically labeled with a frequency, such as 600 MHz. In what region of the electromagnetic spectrum does a photon with this frequency belong?

Understand the electromagnetic spectrum: The electromagnetic spectrum is a range of all types of electromagnetic radiation, which includes radio waves, microwaves, infrared, visible light, ultraviolet, X-rays, and gamma rays. Each type of radiation is characterized by its frequency and wavelength.
Identify the frequency given in the problem: The problem states a frequency of 600 MHz. MHz stands for megahertz, where 1 MHz = 10^6 Hz. Therefore, 600 MHz is equivalent to 600 x 10^6 Hz.
Determine the region of the electromagnetic spectrum: The electromagnetic spectrum is divided into regions based on frequency and wavelength. Radio waves have frequencies ranging from about 3 kHz to 300 GHz. Since 600 MHz falls within this range, it belongs to the radio wave region of the electromagnetic spectrum.
Consider the application of MRI: MRI (Magnetic Resonance Imaging) uses radio waves to create detailed images of the organs and tissues within the body. The frequency of 600 MHz is typical for MRI machines, which utilize radio waves to interact with the nuclei of atoms in the body.
Conclude the region: Based on the frequency of 600 MHz and its application in MRI, the photon with this frequency belongs to the radio wave region of the electromagnetic spectrum.

In the television series Star Trek, the transporter beam is a device used to “beam down” people from the Starship Enterprise to another location, such as the surface of a planet. The writers of the show put a “Heisenberg compensator” into the transporter beam mechanism. Explain why such a compensator (which is entirely fictional) would be necessary to get around Heisenberg’s uncertainty principle.
