Question

Given below are two statements: Assertion (A): Remote sensing is the study of any object without making actual contact with the object under consideration. Reason (R): The electromagnetic radiation reflected or emitted from the object is a common source of remote sensing apart from other sources such as gravity or magnetic fields.

• A. Both A and R are correct and R is the correct explanation of A
• B. Both A and R are correct but R is not the correct explanation of A
• C. A is correct but R is not correct
• D. A is not correct but R is correct

Hint:

Remote sensing obtains information without contact by detecting reflected or emitted energy.

Answer 1

The Correct Option is A

Concept:
Remote sensing is used to obtain information about objects or areas without physical contact.

Step 1: Check Assertion.
Remote sensing studies objects without direct contact. \[ A \text{ is correct} \]

Step 2: Check Reason.
Remote sensing commonly uses electromagnetic radiation reflected or emitted from objects. \[ R \text{ is correct} \]

Step 3: Check explanation.
The reason explains how remote sensing is possible without physical contact. \[ R \text{ correctly explains } A \] \[ \therefore \text{Correct Answer is (A)} \]
