Hi, so in this question, we are given four statements and we have to find out which one of the four describes the correct relationship between the wave speed.
00:13
So we have a wave speed, then wave frequency and the wavelength.
00:24
So we have to find the correct relation between them.
00:29
So let us say that wave speed is denoted by v and wave frequency.
00:35
Frequency is denoted by new or rather let us use f for no confusion to avoid any confusion so the frequency is f and the wavelength is lambda if we know these three units now we need to know what is the exact relation so the exact relation is that the wave speed is equal to the product of the frequency and the wavelength of the wave so this is the relationship between the three now out of the given options we have to find out which one is correct.
01:07
So the option a says that wavelength is equal to the product of the wave velocity and the frequency.
01:15
This we can see here that this does not match.
01:20
So this will be wrong.
01:23
This one is incorrect.
01:25
Now option b says that the wave frequency f is proportional to the wavelength.
01:32
So f is proportional to lambda...
