Problem:Context: In April 2005, the show was revised slightly. Aside from numerous tweakings to the script, there are slight differences in the revised version's musical numbers. Chief among these is a brand new song opening Act II called "Still Rockin."' Other changes include the removal of the' rap' "Dancing is not a Crime". Only the very first section of the rap is used and right before "Mama Says" instead of during the Town Council meeting. Ren gives a speech instead during the meeting. Also, the Reverend's song "I Confess" has also been removed and replaced with a much longer and more emotional scene with Ren after the Town Council meeting and a short reprise of "Heaven Help Me" sung by Reverend Moore alone. Furthermore, the show now begins with Rusty, Wendy Jo, and Urleen singing the opening of "Footloose" instead of Ren and the boys, and during "Learning to be Silent" Ariel sings with Vi and Ethel during the song.

Student A:Electromagnetic radiation can be transmitted through an optical medium, such as optical fiber, or through twisted pair wires, coaxial cable, or dielectric-slab waveguides. It may also pass through any physical material that is transparent to the specific wavelength, such as water, air, glass, or concrete. Sound is, by definition, the vibration of matter, so it requires a physical medium for transmission, as do other kinds of mechanical waves and heat energy. Historically, science incorporated various aether theories to explain the transmission medium. However, it is now known that electromagnetic waves do not require a physical transmission medium, and so can travel through the "vacuum" of free space. Regions of the insulative vacuum can become conductive for electrical conduction through the presence of free electrons, holes, or ions.

Answer this question based on the passage: which type of wave requires a medium for transmission?
Student B:OK... To answer the above question, the relevant sentence is: Sound is, by definition, the vibration of matter, so it requires a physical medium for transmission, as do other kinds of mechanical waves and heat energy.
Sound.
