Video is not accessible in some countries. If you cannot view it, you might need VPN to do so.REVIEW OF WAVE TERMINOLOGY
Use the following DESMOS link to explore the properties of a wave.
TRAVELLING WAVE DESMOS
THE WAVE EQUATION
\( v \) : velocity of the wave (m/s)
\( f \) : frequency in Hz (1/s)
\( \lambda \) : wavelength of the wave (m)
EXAMPLE PROBLEM #1
A water wave has a wavelength of 10cm and is generated by a source with a period of 0.2s. What is the speed of the wave?
EXAMPLE PROBLEM #2
What is the frequency of red light (620 nm)?
