Question

Which all parts give wavelength$\frac{\lambda }{4}$?

Answer 1

1. Wavelength is the distance between two adjacent crests or trough.
2. Wavelength is denoted using $\lambda$.
3. In the figure AE represents a wave AE is $1\lambda$
4. AC represents $\frac{1}{2}\lambda$.
5. AB represents $\frac{1}{4}\lambda or\frac{\lambda }{4}$.
6. Likewise BC, CD, DE give $\frac{\lambda }{4}$.
