How do the following factors affect, it at all, the speed of sound in air:

i. Frequency of sound.

           ii. Amplitude of sound.

          iii. Temperature.

          iv. Humidity.

           v. Pressure.

Dear Student
Factors not affecting the speed of sound are pressure, amplitude, and frequency of the sound wave.
Speed of sound increases with increase in temperature.
Speed of sound increases in proportion to humidity in air. Humidity has a small but significant effect on speed of sound
