Question 382: Waves

Question

Two progressive waves are travelling towards each other with velocity $$50 \mathrm{~m} / \mathrm{s}$$ and frequency $$200 \mathrm{~Hz}$$. The distance between the two consecutive antinodes is

Accepted Answer

Velocity of wave, $$v=f \lambda$$
$$	herefore \quad \lambda=\frac{\mathrm{v}}{\mathrm{f}}=\frac{50}{200}=0.25 \mathrm{~m}$$
$$	herefore \quad$$ Dividing the wavelength for antinodes:
$$\begin{aligned}
\lambda & =\frac{0.25}{2} \
& =0.125 \mathrm{~m}
\end{aligned}$$

Answer

$$0.125 \mathrm{~m}$$

Answer

$$0.150 \mathrm{~m}$$

Answer

$$0.175 \mathrm{~m}$$

Answer

$$0.200 \mathrm{~m}$$
