It is any medium.

Yulia observed a sound wave moving through a solid medium at four different temperatures, and she recorded observations about each one in the chart. Which correctly ranks, from fastest to slowest, the time it will take one wavelength to pass a certain point? Wave X → Wave Y → Wave W → Wave Z Wave Z → Wave W → Wave Y → Wave X Wave X → Wave W → Wave Y → Wave Z Wave Z → Wave Y → Wave W → Wave X

Wave X → Wave W → Wave Y → Wave Z

Why do waves move faster at higher temperatures and in a solid phase? There is more energy and the particles are farther apart. There is less energy and the particles are closer together. There is less energy and the particles are farther apart. There is more energy and the particles are closer together.

There is more energy and the particles are closer together.

Which of these objects would most likely cause a sound wave? a drill laying on its side a nail stuck into a piece of wood a hammer hitting a metal cup a wrench locked in place around a bolt

a hammer hitting a metal cup

Which of these would most likely cause a sound wave? cookies baking milk standing in the bottle a spoon hitting the side of a bowl while mixing butter melting

a spoon hitting the side of a bowl while mixing

The_________of a wave is the density of the medium's particles at the compression of the wave.

amplitude

A wave will go faster through a liquid at _________temperatures.

higher

How many complete wavelengths are present in the sound wave shown? 1 2 4 6

Put the steps in order from 1 to 4 to describe how sound waves travel. Energy is passed from particle to particle: Energy reaches the ear, which allows for hearing: A sound wave is produced when an object vibrates: Energy from the object is transferred to particles around the vibrating object:
