Explanation:
Mechanical waves are waves that requires a medium for their propagation. There are two types of mechanical waves:
- Transverse waves
- Longitudinal waves
Transverse waves are waves that propagates perpendicularly to their source. Examples are electromagnetic waves, ripple on water etc.
Longitudinal waves are waves that propagates parallel to their source. They move in a series of rarefactions and compressions along their path. An example is seismic p-waves
This quantity ρ is known as the density<span> , which is usually defined as the mass per unit volume: ρ = m/V. The volume units milliliter (mL) and cubic centimeter (cm</span>3<span>) are almost identical and are commonly used interchangeably. The general meaning of </span>density<span> is the amount of anything per unit volume.</span>
Answer:
its velocity is 51, or 51.42 to be exact it would be: 51.4285714286
Answer:
Explanation:
First of all, we can find the speed of the sound wave, which is given by:
where
f = 645 Hz is the frequency
is the wavelength
Substituting,
Now we can find the temperature of the air by using the following relationship:
where T is the temperature in Celsius degrees. Since we know v = 322.5 m/s, we can re-arrange the formula to find the temperature:
