Avibrating tuning fork makes 500 vibrations in one second. what is the wavelength of the sound produced if the air temperature is 20°c? group of answer choices

0.500 m
0.686 m
0.343 m
1.46 m
1.87 m

wavelength will be 0.686 m

So option (b) is correct

Explanation:

We have given vibration in one second that is frequency = 500 Hz

We know that velocity of sound is 343 m/sec

We have to find the wavelength

We know that velocity is given by

So wavelength

So wavelength will be 0.686 m

So option (b) is correct

explanation:

earth's surface is mainly heated by the absorption of infrared radiation from the sun.

evaporation occurs because molecules in liquid water are warmed ( usually by the sun) and vibrate quicker, becoming less dense and rise.

condensation occurs because molecules in water vapor are cooled and therefore vibrate more slowly thus becoming more dense and eventually fall to earth.

lines of equal barometric pressure on a weather map are called: isobars : lines of equal temp on a weather map are called: isotherms.​
