Question 187: Waves

Question

length of a string tied to two rigid supports is $$40$$ $$cm$$. Maximum length (wavelength in $$cm$$) of a stationary wave produced on it is

Accepted Answer

This will happen for fundamental mode of vibration as shown in the figure. $${S_1}$$ and $${S_2}$$ are rigid support
Here $${\lambda  \over 2} = 40\,\,\,\,\,\,$$ $$	herefore$$ $$\lambda  = 80\,cm$$
