Common Myths About the Wave Equation ( v = f\lambda )
Let's clear up some common myths about the wave equation, which is written as ( v = f\lambda ):
Wave Speed Misunderstanding: Some people think that wave speed (( v )) changes when the frequency (( f )) changes. But in a certain material, the speed of the wave stays the same.
Confusing Frequency and Wavelength: Many believe that when you increase the frequency, the wavelength also increases. However, they are actually related in the opposite way. The right idea is ( f = \frac{v}{\lambda} ), which shows that if one goes up, the other goes down.
Not for All Waves: This equation mainly works for certain types of waves called sinusoidal waves. Other types of waves might not fit this equation well.
By understanding these points, we can get a better grasp on how waves behave!
