Step-by-Step Solution:
Step 1 of 3

Solution 6DQ The speed of sound in helium is 999 m/s is higher than the speed of sound in air 343 m/s. Since v = f,increasing the speed of sound wave also increases its frequency (its wavelength is unaffected).thus the person voice will become high and squeaky. Or Helium has low density than air,but frequency does not change when sound goes from one medium...
