| But the very same atmosphere is opaque in most frequencies of far infrared, ultraviolet, x-rays and gamma rays. |
| The arm is immobilized in a cast with the elbow in extension, and x-rays are obtained. |
| This energy is often in the form of ionizing radiation like x-rays or gamma rays. |
| The critical angle c below which x-rays can be efficiently scattered from smooth surfaces is quite small, hence the term grazing incidence. |
| Gamma rays are electromagnetic radiation originating in the atomic nuclei, physically identical to x-rays. |
| After x-rays and a lot of fuss, I was sent back to the hostel with some tablets and a cough mixture. |
