# Solution for The Power Radiated by Linear Antenna of Length T is Proportional to - HSC Science (Electronics) 12th Board Exam - Physics

ConceptNeed for Modulation and Demodulation

#### Question

The power radiated by linear antenna of length T is proportional to........................

(λ= wavelength)

1. lambda/ l
2. [lambda/l]^2
3. l/lambda
4. [l/lambda]^2

#### Solution

(d) (l/λ)2

Effective power radiated by the antenna would be too small, because the power radiated by a linear antenna of length ‘l’ into space is (l/λ)2.

As high powers are needed for good transmission, so higher frequency is required which can be achieved by modulation.

Is there an error in this question or solution?
