Chapter 22, Problem 1OQ

To determine

The best statement that describes the difference between radio wave and X-ray.

Answer to Problem 1OQ

Solution:

Option (b): Both can be thought of as electromagnetic waves. They differ only in wavelength and frequency.

Explanation of Solution

Since, radio waves and X-rays both are lying in electromagnetic spectrum, so they are traveling approximately equal to the speed of light.

Since radio waves lie in Infrared regions having frequency 10,000 Hz to 1.0 Hz and wavelength 10.0 km to 1,00,000 km while X-rays lie in Ultraviolet region having frequency ${10}^{18}\text{Hz}$ and wavelength ${10}^{-10}\text{m}\text{.}$

Thus, radio waves and X-rays can be thought of as electromagnetic waves. They differ only in wavelength and frequency.

Conclusion:

Option (b): Both can be thought of as electromagnetic waves. They differ only in wavelength and frequency.
