Wavelength and Frequency
Waves are characterized by their repetitive motion. Envision a toy vessel riding the waves in a wave pool. As the water wave goes under the watercraft, it climbs and down in a normal and rehashed form. While the wave travels horizontally, the boat only travels vertically up and down.
The variable c is the speed of light. For the relationship to hold mathematically, if the speed of light is used in m/s, the wavelength must be in meters and the frequency in Hertz.
All waves can be defined in terms of their frequency and intensity.
c=?? expresses the relationship between wavelength and frequency.
