1. Frequency: Frequency is the number of waves that pass a given point per unit time. Wavelength and frequency are related through the equation c = λν, where c is the speed of the wave, λ is the wavelength, and ν is the frequency.

2. Wave number: Wave number is the reciprocal of wavelength, denoted by k. It is a measure of the number of oscillations per unit length in a wave.

How to Memorize "wavelength"

1. visualize
   

   - Imagine a wave traveling through space or water. The distance between two consecutive crests or troughs is the wavelength.

2. associate
   

   - Associate the concept of wavelength with the idea of periodicity and the distance between crests or troughs in a wave.

3. mnemonics
   

   - Use the mnemonic 'Waves Are Long Periodic Events' to remember that wavelength is a measure of the long periodicity of waves.
