Lower transmit frequency yields greater penetration.

Explanation:
Lower transmit frequency yields greater penetration because attenuation in most media increases with frequency. When the frequency is lower, the wave loses energy more slowly as it travels, so more of the signal reaches deeper regions. This deeper reach comes at a trade‑off: lower frequencies have longer wavelengths, which reduces resolution and detail. So you get deeper penetration at the cost of image sharpness or data precision, which is why lower-frequency waves are chosen when you need to reach deeper targets, while higher frequencies are preferred for finer detail near the surface.
