Chapter 11, Problem 26R

To determine

To choose: The correct option.

Answer to Problem 26R

Option A is correct.

Explanation of Solution

Introduction:

A repeating movement that transfers energy through space or matter is known as wave. A wave that hold electrical field, magnetic field and also, carry energy is known as electromagnetic waves.

Electromagnetic waves with the wavelengths in range of about ten billionths (meter) and about ten-trillionths (meter) are known as X-rays. X-rays penetrate soft tissue and skin, but not the denser materials (bones, teeth). X-rays have shorter wavelengths and high frequencies. So, the correct option is (A).

Option B is incorrect because x-rays have shorter wavelengths and high frequencies.

Option C is incorrect because x-rays have shorter wavelengths and high frequencies.

Option D is incorrect because x-rays have shorter wavelengths and high frequencies.

Conclusion:

Hence, x-rays have shorter wavelengths than UV waves. The correct option is A.
