Question

for a broadcast electromagnetic wave having frequency of 1200 kilo hertz number if waves
that will be formed in 2 kilometre distance are​

Answer 1

Answer:

Explanation:

Given For a broadcast electromagnetic wave having frequency of 1200 kilo hertz number if waves  

that will be formed in 2 kilometre distance are

Given the wavelength of electromagnetic wave

    λ = c / ν

        = 3 x 10^8 / 1200 x 10^3

       = 0.25 x 10^8 x 10^-2 x 10^-3

       = 0.25 Km

Now the number of waves formed in 2 Km distance = n = 2 / 0.25

So n = 8 waves

Answer 2

Answer:

8

Explanation:

number of waves formed in 2km distance is n=2/0.25

n=8
