Can someone explain to me these equations of sound waves?

In summary, the equation for sound waves is v = λf, where v is the velocity of the wave, λ is the wavelength, and f is the frequency. This equation can be used to calculate the velocity of a sound wave by multiplying its wavelength and frequency. The relationship between wavelength and frequency in sound waves is inverse, and the equation shows that the velocity of a sound wave is directly proportional to the product of its wavelength and frequency. For example, if a sound wave has a frequency of 440 Hz and a wavelength of 0.75 meters, its velocity can be calculated as 330 m/s using the equation v = λf.

A bomb explodes on Mars how long will sound waves to travel from Mars to earth??
Ans= 0sec?? or any other answer needs only little hint

means vacuum then sound waves cannot travel??

Yes, exactly.
 
  • #5
so the answer should be cannot travel

Although Mars itself has a dilute atmosphere, so that you will hear an explosion when you are on mars, interplanetary space between Mars and Earth is an almost perfect vacuum, so sound cannot travel from Mars to earth.

Related to Can someone explain to me these equations of sound waves?

1. What is the equation for sound waves?

The equation for sound waves is: v = λf, where v is the velocity of the wave, λ is the wavelength, and f is the frequency.

2. How do you calculate the velocity of a sound wave?

The velocity of a sound wave can be calculated using the equation v = λf, where λ is the wavelength and f is the frequency.

3. What is the relationship between wavelength and frequency in sound waves?

The relationship between wavelength and frequency in sound waves is inverse, meaning that as the wavelength increases, the frequency decreases and vice versa.

4. How do you interpret the equation for sound waves?

The equation for sound waves, v = λf, describes the relationship between the velocity of the wave, the wavelength, and the frequency. It shows that the velocity of a sound wave is directly proportional to the product of its wavelength and frequency.

5. Can you provide an example of how to use the equation for sound waves?

Sure, let's say you have a sound wave with a frequency of 440 Hz and a wavelength of 0.75 meters. Using the equation v = λf, we can calculate the velocity of the wave to be 330 m/s (440 Hz x 0.75 m).
