Question

Match the electromagnetic waves in Column I with their common applications in Column II. 

Column I		Column II
(A)	Gamma rays	(I)	Radar communication
(B)	X-rays	(II)	Cancer treatment
(C)	Microwaves	(III)	Bone imaging
(D)	Radio waves	(IV)	Broadcasting

Choose the correct answer from the options given below:

• A. A-II, B-III, C-I, D-IV
• B. A-I, B-II, C-IV, D-III
• C. A-II, B-IV, C-I, D-III
• D. A-III, B-II, C-IV, D-I

Hint:

Important EM Wave Applications: \[ \boxed{\text{Radio Waves} \rightarrow \text{Broadcasting}} \] \[ \boxed{\text{Microwaves} \rightarrow \text{Radar}} \] \[ \boxed{\text{X-rays} \rightarrow \text{Medical Imaging}} \] \[ \boxed{\text{Gamma Rays} \rightarrow \text{Cancer Therapy}} \]

Answer 1

The Correct Option is A

Step 1: Recall applications of EM waves. \[ \text{Gamma rays} \rightarrow \text{Cancer treatment} \] \[ \text{X-rays} \rightarrow \text{Bone imaging} \] \[ \text{Microwaves} \rightarrow \text{Radar communication} \] \[ \text{Radio waves} \rightarrow \text{Broadcasting} \]

Step 2: Match the columns. \[ A \rightarrow II \] \[ B \rightarrow III \] \[ C \rightarrow I \] \[ D \rightarrow IV \]

Step 3: Identify the correct option. \[ \boxed{A-II,\;B-III,\;C-I,\;D-IV} \] Therefore, \[ \boxed{\text{(A)}} \] is the correct answer.
