Calculate the energy of a photon of electromagnetic radiation his frequency is 6.75×10 to the 12 power s to the -1 power

4.47 × 10^-21 Joules

Explanation:

We are given the frequency of the wave as 6.75 × 10^12 Hz

That is, E = hf

The plank's constant = 6.626 × 10^-34 J-s

Thus;

Energy = (6.626 × 10^-34 J-s × 6.75 × 10^12 Hz)

            = 4.47 × 10^-21 Joules

Hence, the energy of the photon is 4.47 × 10^-21 Joules

the answer is:  

line graphs show patterns in data with variables that change over time; whereas, circle graphs show data as parts out of a whole (such as out of 100%).
