🔍 Key Concepts

• Depth finders use ultrasonic sound waves in water, not radio waves in air • Typical fishfinders and echo sounders operate in the tens to hundreds of kilohertz (kHz) range • Frequencies in plain Hz are in or near the audible sound range for humans

💭 Think About

• First, separate choices that are clearly in the radio communication bands from those that are realistic for sound in water • Ask yourself: which option looks like the ultrasonic range commonly used for depth sounders and fishfinders on small vessels? • Eliminate any answer that would be close to human hearing (20 Hz–20,000 Hz) rather than well above it

✅ Before You Answer

• Check which options are in kHz vs Hz and recall that depth sounders use kilohertz ultrasonic frequencies • Verify that the remaining choice is high enough to be ultrasonic but not so high that it is really a radio communication frequency band • Confirm that the range you pick is one you’ve seen associated with fishfinders/echo sounders (e.g., 50 kHz, 200 kHz) in practice or study materials
