The speed of a wave in a string is $20 m s^{- 1}$ and frequency is $50 H z$ . The phase difference between two points on the string $10 cm$ apart will be

Options:

Answer:

Solution:

$Δ ϕ = \frac{2 π}{λ} Δ x = \frac{2 π}{v} . n . Δ x$

$Δ ϕ = \frac{2 π}{20} \times 50 \times \frac{10}{100}$

$Δ ϕ = \frac{π}{2}$
