A sound wave with a wavelength of 0.82 m passes through air, and then it passes through a glass window, where its wavelength changes to 13 m. If the
sound wave has a constant frequency of 440 Hz, what is its approximate
speed as it passes through the glass? (The equation for wave speed is v= fx
Y.)
A. 3,500 m/s
B. 570 m/s
C. 350 m/s
D. 5,700 m/s
PLEASE HELP ME :(
( the y is supposed to be like
upside down )
