Answer:
C.) 4.85 x 10⁻¹⁹ J
Explanation:
To find the energy, you need to use the following equation:
E = hc / w
In this formula,
-----> E = energy (J)
-----> h = Planck's Constant (6.626 x 10⁻³⁴ J*s)
-----> c = speed of light (3.00 x 10⁸ m/s)
-----> w = wavelength (m)
Once you have converted nanometers to meters, you can plug the given values into the equation and solve.
410 nm 1 m
------------- x ---------------------- = 4.10 x 10⁻⁷ m
1 x 10⁹ nm
E = hc / w
E = (6.626 x 10⁻³⁴ J*s)(3.00 x 10⁸ m/s) / (4.10 x 10⁻⁷ m)
E = 4.85 x 10⁻¹⁹ J
