Question

complete process (given, required, equation, solution)

1) What is the energy of a photon of violet light with a frequency of 7.00 x 1014 Hz?

2) What is the energy of a photon of orange light with a frequency of 5.00 x 10-7 Hz?

3) What is the energy of a photon of blue light with a frequency of 6.50 x 1014 Hz?

Answer 1

1)

$$E=hf\\E=(6.626\cdot10^{-34})(7\cdot10^{14})=4.6\cdot10^{-19}\ J$$

2)

$$E=hf\\E=(6.626\cdot10^{-34})(5\cdot10^{-7})=3.3\cdot10^{-40}\ J$$

3)

$$E=hf\\E=(6.626\cdot10^{-34})(6.5\cdot10^{14})=4.3\cdot10^{-19}\ J$$
