Properties of Light - variables?

[Saleha_Mian_3E]

Hi I know that a property of light is electromagnetic radiation, but what are the variables that equal the speed of light? and what do the variables stand for?

If you are asking what is the variable that is the speed of light that would be c which is 3E8. If you asking the formula it would be c= wavelength(meters) times frequency in Hz.

Hi! Can you clarify what you variables you want defined? As for what is the variable for the speed of light, the variable is c which is 3.00 * 10^8 m/s and it is found in the

lambda = h*c/E equation
lambda= wavelength
h= Planck's constant which is 6.626*10^-34 J*S
and E is the total energy emitted of a photon which is not to be confused with the work function which is energy needed to remove an electron. This is in joules!
