Answer:
The waves interfere destructively occur. The further explanation is given below.
Explanation:
The transmissions almost commute with either the speed of light. So, use the following relation to calculate the wavelength of that same TV signal.
⇒ λ = [tex]\frac{c}{v}[/tex]
⇒ = [tex]\frac{3\times 10^{8}m/s }{75 \ MHz(\frac{10^{6}Hz}{1 \ MHz})}[/tex]
⇒ = [tex]4 \ m[/tex]
The variance in the route between both the 2 waves that approach the recipient is 248 m, also because wave passes 124 m two times. And then after the plane's reflective thinking the waves iteration adjustments by half.
⇒ Δ[tex]x[/tex] = [tex](m+\frac{1}{2} )[/tex] λ
If the value of the above expression is a positive integer, the waves interfere constructively, as well as the waves disrupt destructively if they are integral multiples of the half. Caused by a change of step due to the reflection the component of half would be added.
⇒ [tex]248 \ m=(m+\frac{1}{2})(4 \ m)[/tex]
⇒ [tex]m = 61.5[/tex]
Since the value of m seems to be an integral multiple of the half.
Therefore, the waves interfere destructively
