Detailed explanation-1: -The frequency of a wave is inversely proportional to its wavelength. That means that waves with a high frequency have a short wavelength, while waves with a low frequency have a longer wavelength.
Detailed explanation-2: -Conclusion: a longer wavelength means a lower frequency, and a shorter wavelength means a higher frequency!
Detailed explanation-3: -Light of longer wavelength is scattered much more than the light of shorter wavelength.
Detailed explanation-4: -Wavelength is one way of measuring the size of waves. It is the distance between two corresponding points on adjacent waves. In a transverse wave, particles of the medium vibrate up and down at right angles to the direction that the wave travels. The wavelength of a longitudinal wave can be measured as the distance.
