An electromagnetic wave travels in a vacuum. The wavelength of the wave is tripled. How is this accomplished? by tripling the frequency of the wave by tripling the magnitudes of the electric and magnetic fields that comprise the wave by reducing the frequency of the wave by a factor of three by reducing the speed of the wave by a factor of three by tripling the speed of the wave

The speed of sound in ice, water, and steam is shown. what best explains the speed of sound in different states of matter? sound travels fastest in ice because energy is easier to transfer when the molecules are close together. sound travels slowest in steam because the sound has to move around the gas molecules that are far apart. sound travels fastest in ice because the temperature of solids is always greater, so the heat transfers the sound energy. sound travels slowest in steam because the pressure is so great the sound cannot travel though the steam particles.

In the first law of thermodynamics, triangle e=q-w, what does q stand for

How will the system respond to a temperature increase?
