Two musicians are playing the same instruments. the first one emits the sound with correct wavelength 58 cm while the second one is off, and the wavelength is 5 mm longer.
a) what is the frequency of the beats when they play together?
b) by how much does the second musician need to change her instrument’s wavelength so that thefrequency of the beats is reduced to 1 hz?

Explanation:

Given

Wavelength of first musician

Wavelength of second musician

Frequency of first musician

where v=velocity of sound

Frequency of beat

(b)If beat frequency is reduced to 1 Hz then

for

a) electrical > light, sound, and thermal< < < <

) the mechanical energy of the firefighter moving.< < < < a) electrical > light, sound, and thermal< < < <

c) both a and b.

the inner core.

good luck: )
