Question

X-rays are?

• A. Stream of electrons
• B. Stream of positively charged particles
• C. Electromagnetic radiations of high frequency
• D. Stream of uncharged particles

Hint:

X-rays are a type of electromagnetic radiation, distinct from particle-based radiation like alpha or beta particles. Their high frequency allows them to penetrate materials for imaging purposes.

Answer 1

The Correct Option is C

X-rays are a form of electromagnetic radiation, not a stream of particles. They have high frequencies, typically higher than ultraviolet light, and can penetrate through various materials, which is why they are commonly used in medical imaging and industrial applications. The key characteristics of X-rays include:
- Electromagnetic radiations of high frequency: X-rays belong to the electromagnetic spectrum, with wavelengths shorter than ultraviolet light. This high frequency gives them the ability to penetrate solid objects, making them useful for imaging inside the body.
- Stream of electrons, positively charged particles, or uncharged particles: These options refer to particle-based forms of radiation like cathode rays or alpha particles, not X-rays, which are pure electromagnetic waves.
Therefore, the correct answer is that X-rays are electromagnetic radiations of high frequency.
