Wavelength

Q. Transverse waves are generated in two uniform wires $A$ and $B$ of the same material by attaching their free ends to a vibrating source of frequency $200\text{Hz}$. The cross-sectional area of $A$ is half that of $B$ while the tension on $A$ is twice that on $B$. The ratio of the wavelengths of the transverse waves in $A$ and $B$ is

1. $1:\sqrt{2}$
2. $\sqrt{2}:1$
3. $1:2$
4. $2:1$

Q. A longitudinal wave is produced on a slinky toy. The wave travels at a speed of $30\text{cm/s}$ and the frequency of the wave is $20\text{Hz}$. What is the minimum separation between two consecutive compressions of the slinky toy ?

1. $2.5\text{cm}$
2. $0.5\text{cm}$
3. $1.5\text{cm}$
4. $1.8\text{cm}$
