Frequency and energy are related based on the equation eqEhupsilon eq where E refers to energy h refers to the Plancks constant and equpsilon eq refers. Notice the final statement does not match up to the math equations above. For example red light has a wavelength of around 620 740 nm and blue light has a wavelength of around 445 500 nm.
Before calculating give some thought to the relationship between frequency and wavelength.
The amplitude can be read straight from the equation and is equal to A. C the speed of light 300000 kms or 30 x 10 8 ms the wavelength of light usually measured in meters or Angstroems 1 A 10-10 m. The wavelength of visible light ranges from deep red roughly 700 nm to violet roughly 400 nm for other examples see electromagnetic spectrum. The first three statements are true.
