Question

the magnatic field in a plane electromagnatic wave is given by B y =5* 10^-7 sin [ 2π*10^8 t+2π/3 x ] tesla. find (i) wavelenght (ii) frequency.​

Answer 1

Answer:

The magnetic field in a plane of electromagnetic wave is given by

B=2×10

−7

sin(0.5×10

3

x+1.5×10

11

t)

from the above, K=0.5×10

3

= propagation constant

K=

λ

2π

where, λ= wavelength of wave

λ=

0.3×10

3

2×3.14

λ=1.256×10

−2

m

λ=1.256cm

The electromagnetic wave is Microwave radiation in spectrum
