Question

An open organ pipe emits G (392 Hz ) when the temperature is 14 C. The speed of sound in air is v(331+0.60T)m/s, where T is the temperature in C.

Part A

Determine the length of the pipe.

Express your answer to three significant figures and include the appropriate units.

l = (???) (Units)

Part E

What is the wavelength in the traveling sound wave produced in the outside air?

Express your answer to three significant figures and include the appropriate units.

l = (???) (Units)

Part E

What is the wavelength in the traveling sound wave produced in the outside air?

Express your answer to three significant figures and include the appropriate units.

Explanation / Answer

A) v = 331 + 0.6*14

= 339.4 m/s

f = 392 hz

apply, f = v/(2*L)

==> L = v/(2*f)

= 339.2/(2*392)

= 0.433 m

E) v = lamda*f

==> lamda = v/f

= 339.4/392

= 0.856 m
