wavelength:
A. is halved B. is doubled
C. remains
constant D. increases
9. Radio waves are similar to light

of the sound in air
D. amplitude of vibration of the vocal
chords.
15. A mobile telephone involves the transfer of waves. The voice
sounds must be converted into other types of waves because:

through the same medium.
C. sound waves can not travel in a vacuum
D. sound is a longitudinal wave.
