In summary, the conversation discusses the concept of wavelength and its application to electrons, as well as the difficulty in visualizing this concept. It is explained that wavelength is simply the distance between two crests of a wave, and that it can be measured in various way...
Define the � frequency’ and � time period’ of a wave What is the relation between the two - Frequency: Number of cycles or vibration in one second is known the frequency. SI unit of frequency is $per second$ and it is also written as $Hz$.Time pe
On the basis of limit of wave motion: If any wave advances through a medium continuously with a definite velocity, the wave is called a travelling or progressive wave. If the wave is not damped, it can propagate up to infinity. On the other hand, if the wave does not advance, but rem...
