An orchestra contains both string and wind instruments. The orchestra tunes their instruments in the morning at a temperature of TC = 15 °C. As they play, the temperature rises in the afternoon to TH 30 °C and falls in the late evening back to TC. As usual, the speed of sound in air increases with increasing temperature.

How has the increase in temperature from the morming to the afternoon altered the speed of sound in the air?

1. The temperature increase has not changed the speed, wavelength, or frequency of the sound.
2. The temperature increase has not altered the speed of sound in air; it's only decreased the frequency of the sound.
3. The temperature increase has not altered the speed of sound in air; it's only increased the frequency of the sound.
4. The temperature increase has increased the speed of sound in air
5. The temperature increase has not altered the speed of sound in air, it's only decreased the wavelength of the sound.
6. The temperature increase has decreased the speed of sound in the air increase has not altered the speed of sound in air, it's only increased the wavelength of the sound.
