Answer 1

Explanation:

Answer :-

• Velocity of the wave \leadsto⇝ \boxed{\tt{\red{330\:m/s}}}

330m/s

Given :-

• Frequency (f) = 250 Hz

• Wave length (\lambdaλ ) = 1.32 m

To find :-

• Velocity of the wave

Formula used :-

• \boxed{\sf{\purple{v = f \times \lambda}}}

v=f×λ

Solution :-

\sf{➪\:v = f \times \lambda}➪v=f×λ

\sf{➪\:v = 250 \times 1.32}➪v=250×1.32

\sf{➪\:v =}➪v= \bold{\red{330\:m/s}}330m/s
