Answer:

4.4 x 10⁻¹⁹ J

Step-by-step explanation:

To find the energy of the photon, you need to use the following equation:

E = hf

In this equation,

-----> E = energy (J)

-----> h = Planck's Constant (6.626 x 10⁻³⁴ J·s)

-----> f = frequency (Hz)

You can plug the given value and constant into the equation and solve for "E". The final answer should have 2 sig figs like the given value (6.7 x 10¹⁴ = 2 sig figs).

E = hf <----- Given equation

E = (6.626 x 10⁻³⁴ J·s)(6.7 x 10¹⁴ Hz) <----- Insert values

E = 4.4 x 10⁻¹⁹ J <----- Multiply
