Question

the distance between 2crest and 6 trough of wave us 24 cm . if wave velocity is 2ocm then frequency is

Answer 1

Yeah! Physics is easy one subject, you just need a good tutor and observation to understand it. Let’s solve your problem, as you can see and I assume you know the definition of wavelength i.e the wavelength is the consecutive distance between two points hence for example if we define it in terms of crest: a wavelength is the consecutive distance between two crests. easy one right?

Now as from the mage explains the wavelength will be 30 cm.
