[tex]\large\underline{\mathbb{PROBLEM}}:[/tex]
A wave has a wavelength of 18 meters and frequency of 5 Hz. What is its velocity?
[tex]\large\underline{\mathbb{SOLUTION}}:[/tex]
- To find the velocity or the speed of a wave use the formula v = f λ. Just multiply the wavelength and the frequency.
[tex] \begin{gathered} \begin{gathered}\begin{gathered}\boxed{\begin{array}{l} \rm\red{\: \: \: \: \: \: \: \: \: \: \: \: \: \: Stands \: for:} \\ \\ \sf{v \: = \: the \: speed \: of \: the \: object} \\ \sf{f \: = \: the \: frequency \: of \: the \: object} \\ \sf{\lambda \: = \: the \: wavelength \: of \: the \: object}\end{array}}\end{gathered} \end{gathered}\end{gathered} [/tex]
Then you know the meaning, now let's solve.
- [tex]v = f \lambda [/tex]
- [tex]v \: = \: (5\: Hz) \: ( 18 \: m)[/tex]
- [tex]v \: = \: 90 \: m/Hz[/tex]
[tex]\large\underline{\mathbb{ANSWER}}:[/tex]
- The velocity of the wave is 90 m/Hz.
