4 refraction​

Answer 1

reflection..............

Answer 2

Answer:

(1) The velocity of sound in the sea can be determined by the sounding machine.

Explanation:

A Sound Velocity Sensor is a device that measures sound velocity in a body of water.

The device's Sound Velocity Profiler detects the speed of sound as it travels through the water column.

The speed of sound in water can be measured by sending a small acoustic signal to a receiver at a given distance or by measuring the variables that affect sound velocity in water, such as salinity, temperature, and pressure.
