In an earlier physics course you learned about waves (sound waves, waves on the strings of musical instruments, etc.). Describe the main difference between longitudinal waves and transverse waves. Based on what you have learned in the lecture part of this course, which of these two types is an electromagnetic wave? What is vibrating as an electromagnetic wave propagates?

6 cos 34, 6 sin 34 trig

there is no correct list among the choices you've provided.

the list might look something like this:

-- baby human

-- piccolo

-- flute

-- soprano singer

-- trumpet

-- tenor singer

-- trombone

-- baritone singer

-- baritone horn

-- bass singer

-- tuba

since i had to make up the list myself, i made it easy on myself, and i didn't try to shuffle the string instruments and woodwinds into it too.
