Question

Please answer!

Ocean waves are hitting the seashore at a rate of 15 Hz. The distance between two successive crests is 3 m. Calculate the speed of the ocean waves. (note: crest/s = 1 Hz)​

Answer 1

`\sf \\u \: = \lambda * \upsilon`

• λ = Wavelength [Given = 3 m]
• υ = Frequency [Given = 15 Hz]
• ν = Speed [To find]

`\sf \\u = 3 * 15`

`\sf \\u \: = 45 \: m/s`

➪The speed of ocean waves is 45 m/s...~
