Have you seen animations or videos of this situation? As with transverse waves, the spring constant and the linear mass density enter into the equations, right?bolzano95 said:I didn't quite understand my professor when he defined the speed of longitudinal wave.
Lets say I have a slinky and on one side we act with a force F along the slinky. Well, he said that this part then starts to move with velocity v.
But how? v isn't constant...
The speed of a longitudinal wave can be calculated by multiplying the wavelength of the wave by its frequency. This equation is represented as v = λ * f, where v is the speed in meters per second, λ is the wavelength in meters, and f is the frequency in hertz.
The speed of a longitudinal wave can be affected by the medium through which it travels, the temperature of the medium, and the elasticity of the medium. In general, waves travel faster in denser and more elastic materials, and at higher temperatures.
Yes, the speed of a longitudinal wave can change if it travels through a different medium. Each medium has its own specific properties that can affect the speed of a wave traveling through it.
The speed of a longitudinal wave is usually slower than the speed of a transverse wave in the same medium. This is because longitudinal waves require particles in the medium to vibrate in the same direction as the wave is traveling, which can be slower than the transverse motion of particles in a transverse wave.
Calculating the speed of a longitudinal wave is important because it helps us understand how energy is transferred through different mediums. It also allows us to predict the behavior of waves in different situations and can be used to measure important properties of materials, such as elasticity and density.
