Radio waves have the longest wavelengths
Answer:
The length of the beam increasing is 9.64 ft/s.
Explanation:
Given that,
Height = 210 ft
Distance =290 ft
According to figure,
We need to calculate the angle
....(I)
Put the value of x in the equation
Now,
On differentiate of equation (I)
Put the value in the equation
Hence, The length of the beam increasing is 9.64 ft/s.
