WebElectromagnetic waves are transverse waves with a wide range of properties and uses. The reflection and refraction of light explains how people see images, colour and even optical illusions. Web8. A sonar system on a boat sends an ultrasound pulse towards the seabed. The pulse is reflected, and it is detected 0.2 s later by the system. Calculate the depth of water if the speed of sound in water is 1 480 m/s. 148 m.
