Assertion (A): Free space does not interfere with normal radiation and propagation of radio waves
Reason (R): Free space has no magnetic or gravitational fields.
The correct answer is option 'A', which states that both the assertion and the reason are correct, and the reason is the correct explanation of the assertion.
Explanation:
In order to understand why the given assertion and reason are correct, let's break down each statement individually.
Assertion (A): Free space does not interfere with normal radiation and propagation of radio waves
- Free space refers to the absence of any material medium or objects. In free space, there are no obstacles or obstructions that can disrupt the propagation of radio waves.
- Radio waves are a form of electromagnetic radiation. They consist of electric and magnetic fields that oscillate perpendicular to each other and propagate through space.
- Since free space is devoid of any material objects, there are no physical barriers or obstacles that can interfere with the normal radiation and propagation of radio waves.
- Therefore, the assertion is correct.
Reason (R): Free space has no magnetic or gravitational fields.
- Free space, also known as a vacuum, is a region where there is no matter or particles. It is empty of any substance.
- Magnetic fields and gravitational fields are produced by the presence of matter or particles with mass. In free space, there are no such particles or matter to create magnetic or gravitational fields.
- Without magnetic or gravitational fields, there are no additional forces or influences that can interfere with the propagation of radio waves.
- Therefore, the reason is correct.
Explanation of Reason (R) being the correct explanation of Assertion (A):
- The reason provided explains why free space does not interfere with the normal radiation and propagation of radio waves.
- Magnetic and gravitational fields can interact with electromagnetic waves and affect their propagation. However, in free space where there are no magnetic or gravitational fields, radio waves can propagate freely without any interference.
- The absence of these fields in free space ensures that radio waves can travel undisturbed and at the speed of light.
- Therefore, Reason (R) provides a valid explanation for Assertion (A).
In conclusion, both Assertion (A) and Reason (R) are correct, and Reason (R) is the correct explanation of Assertion (A).
