point with regards to frequency. The speaker is much smaller than the wavelength of the frequency being produced, so it is acting as a point source.
speaker to radiate equally in all directions"? Would this be akin to measuring the output bare light bulb without a reflector where the spherical surface area, 4∏r^2, comes into play?
When the size of the speaker is small (less than 1/4 of the wavelength is one standard used in physics texts) then yes, all sound will radiate equally in all directions. The intent of the question is that the speaker is a point source, so the speaker surface area does not come into play.
That gives an idea for another question in the future. Thanks!
