Answer 1

The technology developed in 1922 that matches the student's question is the echo sounder. This instrument accurately measures ocean depth using sonar by reflecting sound waves off the seabed.

Step-by-step explanation:

The technology or concept that was developed in 1922 according to the question is likely the echo sounder, as it aligns with historical advancements in oceanic navigation and measurement technologies during that time period. Echo sounders use sonar (Sound Navigation And Ranging) to determine the depth of the ocean by sending out a sound wave that reflects off the seabed. This technology significantly improved accuracy in measuring ocean depth compared to the older method using a fathom, which involved dropping a knotted rope overboard.
