- 21. Multiple Choice
In the diagram, the mountaineer can hear the stream although he cannot see it. When he is closer to the gully, he can both hear and see the stream. When he is further from the gully, he can neither hear nor see the stream.
Which statement is NOT correct?
As he approaches the gully edge, the sound becomes louder.
As he approaches the gully edge, he hears first the short wavelength, higher frequencies and then the long wavelength, lower frequencies.
He hears the stream because some of the sound is diffracted.
He hears the stream because some of the sound is reflected from the opposite wall of the gully.
