Answer:
A.) 3.3 x 10⁻¹⁸ J
Step-by-step explanation:
You can calculate the energy using 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)
Therefore, you can plug the given values into the equation and solve for "E".
E = hf <----- Equation
E = (6.626 x 10⁻³⁴ J*s)(5.0 x 10¹⁵ Hz) <----- Insert values
E = 3.3 x 10⁻¹⁸ J <----- Multiply
