Question

farah is doing an experiment that involves calculating the speed of a longitudinal wave. what will most likely happen if she increases the temperature in the room? the amplitude of the wave will increase. the amplitude of the wave will decrease. the speed of the wave will increase. the speed of the wave will decrease.

Explanation:

The speed of a longitudinal wave (such as sound in air) is directly proportional to the square - root of the absolute temperature of the medium. When the temperature increases, the speed of the wave increases. Amplitude is related to the energy of the wave source and not directly to temperature.

Answer:

The speed of the wave will increase.
