How long is the sound wave if frequency is 320 Hz? Speed of sound =340 m/s

λ =v/f=330/320 = ... m

calculate the heat energy absorbed when 1.5kg of paraffin is raised from 15 degrees celsius to 50 degrees celsius

To determine the length of a sound wave, you can use the formula:

Length = Speed of sound / Frequency

Given that the frequency is 320 Hz and the speed of sound is 340 m/s, you can calculate the length as follows:

Length = 340 m/s / 320 Hz
= 1.0625 m

Therefore, the length of the sound wave is approximately 1.0625 meters.
