Question:

Which statements are true for X-ray?

(A) The wavelength range of X-rays is about $10^{-8} m$ to $10^{-13} m$.
(B) X-rays can't affect a photographic film.
(C) X-rays can damage living tissues.
(D) We can generate X-rays by bombarding a metal target by high energy electrons.
(E) The wave length of X-rays is more then Microwave.

Choose the correct answer from the options given below:

Options:

(A), (B) and (E) Only

(B), (C) and (D) Only

(A), (C) and (D) Only

(A), (D) and (E) Only

Correct Answer:

(A), (C) and (D) Only

Explanation:

The correct answer is Option (3) → (A), (C) and (D) Only

(A) The typical wavelength range of X-Rays is between $10^{-8}m (100 nm)$ and $10^{-13}m(0.01nm)$ which falls within X-Ray region.

(C) X-Rays are ionizing radiation, which means they have enough energy to remove electrons from the molecules, potentially causing damage to living tissues and DNA.

(D) X-Rays are commonly generated in X-ray tubes by bombarding a metal target with high energy electrons.
