A sound wave has a frequency of 634 Hz in air
and a wavelength of 0.47 m.
What is the temperature of the air? As-
sume the velocity of sound at 0°C is 333 m/s.
Answer in units of °C.

Explanation:

The frequency and the wavelength of a wave are related by the equation

where

v is the speed

f is the frequency

is the wavelength

For the sound wave in this problem, we have

f = 634 Hz (frequency)

(wavelength)

Therefore, the speed of the wave is

The speed of sound in air depends on the temperature according to the equation

where T is the temperature.

In this problem, we know the speed, so we can calculate the temperature:

fire could start, buildings collapsing, and ash falling from the sky.

explanation:

this is because the buildings or plants could catch on fire and the buildings would most likely collapse. lastly ash would fall because all the burning would cause ash to fall from the sky.

hope this .
