- 1Transverse waves- Transverse waves are waves in which the vibrations of the particles or medium in which the waves travel are at a right angle to the direction of the waves. Longitudinal waves- Longitudinal waves are waves in the vibrations of the particles or medium in which the wave travels are in same direction as to that in which the wave travels.Frequency of waves-The frequency of a wave is a measure of the number of waves made by a source each second, or the number of waves that pass through a particular point in the medium each second.The equation he measure the frequency is frequency times wavelength.
- 2Important points - The speed of a wave is affected by the medium in which the wave is travelling through or along. A change in wave causes a change in the wavelength but not the frequency because that cannot change.Reflection in use- A periscope is an optical instrument used predominately in submarines so that the crew can see what is happening above water without having to surface.
