Answer 1

$\huge\bold{Answer}$

$\huge\bold{Wavelength}$ :-

Wavelength is the distance between two adjacent points in a wave.

Wavelength is inversely proportional to $\bold{frequency}$. It means that if two waves are travelling at the same speed , the wave with a higher frequency will have a shorter wavelength .

And , If one wave has a longer wavelength than another wave , will also have a lower frequency if both waves are travelling at the same speed.

Formula to determine or calculate wavelength is :-

Wavelength = wavespeed / frequency .
