Question

8 what can you conclude about x-rays from the fact that they diffract? a they travel fairly slowly b they cannot pass through most obstacles c they travel in waves d they carry a lot of energy

Explanation:

• Option A: X - rays are electromagnetic waves that travel at the speed of light (very fast), so this is incorrect.
• Option B: X - rays can pass through many obstacles (like human tissue for medical imaging), so this is incorrect.
• Option C: Diffraction is a property of waves. Since X - rays diffract, it implies they travel in waves. This is correct.
• Option D: While X - rays do carry energy, the fact that they diffract is related to their wave - like nature, not directly to the amount of energy they carry. So this is not the conclusion from diffraction.

Answer:

C. They travel in waves
