Daily Quiz Atomic Emission Spectrum

The formula for the radiative energy (E) carried by a photon of light is:

• E = h x c

• E = c/λ

• E = h x f

• E = mMG/d

The speed of electromagnetic radiation:

• depends on the form of radiation

• is always 3 x 10⁸ m/s, regardless of the type

• decreases as distance increases

• is 6.626 x 10^-34 J x s
