The computation for this problem would be:

The formula that we will be using is: f = c/λ

Where:

c = speed of light = 3.00 x 10^5 km/s convert it to meters, so: 3.00 x 10^8 m/s 

λ = wavelength of the microwave radiation = 3.50 cm convert this to meters, so: 0.035 m 

f = frequency (in Hertz) 
f = c/λ

= 3.00 x 10^8 m/s / 0.035 m 

f = 8.57 x 10^9 Hz Frequency

<span>c = speed of light = 3.00 x 10^5 km/s = 3.00 x 10^8 m/s
  λ = wavelength of the microwave radiation = 3.50 cm = 0.035 m
  f = frequency (in Hertz) = to be determined
    f = c/λ = 3.00 x 10^8 m/s / 0.035 m
  f = 8.57 x 10^9 Hz Frequency</span>

Which direction does air circulate into low pressure zones in the northern and southern hemisphere
Yuri [45]
<span>Now consider a low pressure area on a disk as shown below.A parcel of air at point A would move toward the center of the low pressure area. That movement would take it farther away from the center of the disk and therefore it would move to the west. A parcel of air at B would move toward the center of the low pressure area which would also take it closer to the center of the spinning disk where its speed is greater than the surrounding points. It would appear to move to the east. With A moving to the west and B moving to the east the line from A to B is rotating counterclockwise.</span>
