Chapter 27, Problem 7A

To determine

Whether light is simply a small portion of available electromagnetic spectrum.

Explanation of Solution

Introduction: Electromagnetic spectrum is collection of all the available frequencies ranges from radio waves, microwaves, infrared radiation, visible light, ultraviolet, x rays, and gamma rays $\left(1\text{ Hz to 1}{0}^{24}\text{ Hz}\right)$ .

As we go through the electromagnetic spectrum containing all types radiation, we find that the small region of spectrum is associated with visible light ranges from ${10}^{15}\text{ to }{10}^{16}\text{ Hz}$

Conclusion: Yes, light spectrum is small portion of available electromagnetic spectrum.
