Question

100
A wave, 10 m from crest to crest, moving past
the observer at a rate of 20 wave cycles per
second. What is the velocity of wave?
A) 200 m/s​

Answer 1

Answer:

Step-by-step explanation:

The nature of a wave was discussed in Lesson 1 of this unit. In that lesson, it was mentioned that a wave is created in a slinky by the periodic and repeating vibration of the first coil of the slinky. This vibration creates a disturbance that moves through the slinky and transports energy from the first coil to the last coil. A single back-and-forth vibration of the first coil of a slinky introduces a pulse into the slinky. But the act of continually vibrating the first coil with a back-and-forth motion in periodic fashion introduces a wave into the slinky.
