The equation of a wave travelling on a string is $y = sin [20 π x + 10 π t]$ , where x and t are distance and time in SI units. The minimum distance between two points having the same oscillating speed is :

Options:

Answer:

Solution:

Minimum distance between 2 points having same speed is $\frac{λ}{2}$ .
$λ = \frac{2 π}{k} = \frac{1}{10} m = 10 cm$
$Distance = \frac{λ}{2} = 5 cm$
