Answer:
Both Technician A and Technician B are correct
Explanation:
Air tools and electric tools are both power tools as they are used to make work easier. Air tools generally use an air compressor that powers the motor of the tool making it possible to use it while electric tools as the name implies are powered by an electric source which in this case is batteries. An example of an air tool is the nail gun which can be used by furniture makers to drive nails and they are often louder than electric tools because of vibrations caused by the compressor making it necessary to use ear protection when using the tool for ear safety.
Technician B is also correct because it is always advisable to use impact sockets while using impact guns due to the ability of the impact sockets to withstand the force caused by operating impact guns and make work neater when nuts and bolts are being loosened or tightened.

Answer:
0.226m or 22.6cm
Explanation:
using the formula: (v = f * lambda), we can rearrange to form (lambda = v / f)
The calculation is 3x10^8/1.33x10^9 which equals 22.6cm to 3 sig fig.
This is assuming the wave mentioned in the question is an electromagnetic wave though, so that we can use a value for the wave's speed. If it was supposed to be another type of wave, the question is not possible without specifying the speed.
