Final answer:
The statement about the penetration depth of AR-8150PX-45 PowerPick being 6mm is false since the actual effective penetration depth is 3.85 cm, which is adequate for an eye examination. The wavelength of ultrasound in 0°C air is given as 16.6 μm.
Step-by-step explanation:
The depth of penetration for the new AR-8150PX-45 PowerPick is not 6mm. This statement is false because the effective penetration depth given is 3.85 cm, which is sufficient to examine the eye thoroughly.
For the ultrasound question, considering that the effective penetration depth required to examine the entire eye is approximately 3.00 cm, the given 3.85 cm depth is enough to examine the entire eye. Regarding the wavelength of such ultrasound in 0°C air, we can refer to the information (c) 16.6 μm as the wavelength, which would be pertinent to ultrasound in different contexts.
