I'll start off.
Two performers are playing the same note at the same time, but slightly out of tune, so that beats are heard in the
sound. If the frequencies are 440 Hz and 446 Hz, how many beats are heard each second?
a) 443 beats / sec
b) 12 beats / sec
c) 6 beats / sec
d) 223 beats / sec

Remember to hide the answer (use [hide] [/hide])

Just for fun...
[hide] 6 beats per second [/hide]

EDIT: Apparently hiding my answer isn't working. Whoops.

I am just going to make a new question:
What is an antinode? A node? What is a standing wave pattern?

The anti-node in a wave function is the point that has the highest displacement (amplitude), while nodes are the points of a wave that have minimal to zero displacement. These two points are both typically found in standing waves, which remain in a constant position. Examples of this are guitar strings or xylophone/marimba bars.

Next question: name two environmental factors that can affect the speed of sound.

Temperature, and Wind Conditions?

I was gonna say temperature and altitude, but those really affect it in the same way.

So do I get it right :O. I do see how altitude would affect it as well
