Question

Consider the following statements X-rays.
1. They can pass through thin sheets of aluminium.
2. They can be deflected by magnetic field.
3. They move with a velocity less than the velocity of ultraviolet rays in vacuum.
Which of the statement(s) given above is/are correct?

• A. 1, 2 and 3
• B. Only 1
• C. 2 and 3
• D. 1 and 2

Answer 1

The correct option is B Only 1

Since X rays are very energetic rays, so these can pass through thin aluminium sheets.
X-rays, being electromagnetic rays, are neutral. Thus X-rays cannot be deflected by magnetic field.
Also, X-rays and ultraviolet rays are electromagnetic rays. So both move with same speed in vacuum.
Hence, only statement 1 is correct.
