Radiology Practice Test

X-rays that are exposed in the mouth are high or low energy?

1. High energy (short wavelengths)

2. Low energy (long wavelengths)

3. No specific energy

4. Medium energy

The correct answer is: High energy (short wavelengths)

X-rays that are exposed in the mouth are high energy because they have short wavelengths. X-rays with shorter wavelengths have higher energy levels compared to those with longer wavelengths. Option B, low energy with long wavelengths, is incorrect because X-rays used in dental imaging have a high amount of energy to produce clear images. Option C, no specific energy, and Option D, medium energy, do not accurately describe the energy levels of X-rays used in mouth X-rays. Therefore, A, high energy with short wavelengths, is the correct answer.
