Question

If a water wave has a wavelength of 1.0 m and a frequency of 2.0Hz (Hertz), how long will the wave take to travel 20. m from a boat to the shore?

Answer 1

wave speed=frequency( hertz)×wavelength( metre)

Answer 2

Yeah I calculated it. Thx

Answer 3

then whats the annswer u got?

Answer 4

wave speed= 2⋅1=2ms^−1

Answer 5

Time taken to travel 20m.

Answer 6

time=Distance/Speed

Answer 7

I got 10s as an answer.

Answer 8

\[t=\frac{ 20m }{ 2\frac{ m }{ s } }\]

Answer 9

so, T= 10s
It takes 10 seconds to travel 20 metres.

Answer 10

did this help?

Answer 11

yeah thx
