As the temperature of the air increases, what happens to the velocity of sound? (Assume that all other factors remain constant.).
The intensity of a point source at a distance d from the source is I. What is the intensity at a distance 2d from the source?
A small vibrating object on the surface of a ripple tank produces waves of frequency 20 Hz and speed 60 cm/s. If the source S is moving to the right as shown the figure, with a speed of 20 cm/s.
What frequency would an observer at point C hear?

30 Hz.
13.3 Hz.
6.7 Hz.
In general, sound is conducted fastest through
What determines "loudness" of a musical note?
