Assertion (A) : Audio signal of frequency 10 kHz cannot be transmitted over long distance without modulation. Reason (R) : Length of the antenna required \(\frac{\lambda}{4}\). |
Both (A) and (R) are true and (R) is the correct explanation of (A). Both (A) and (R) are true but(R) is NOT the correct explanation of (A). (A) is true but (R) is false. Both (A) and (R) are false. |
Both (A) and (R) are true and (R) is the correct explanation of (A). |
The length of antenna required for this transmission will be : \(\lambda\) = \(\frac{c}{\nu}\) c = 3 x 108 m/s ; \(\nu\) = 10 x 103 Hz The length of antenna required for this transmission : l = \(\frac{\lambda}{4}\) = 7500 m |
