Calculate the energy of a photon of green light with a frequency of 5.96 ✕ 10^14 s−1
I keep getting 3.88e-21, but the quiz keeps saying I'm wrong...
nevermind i got it, accidentally put in 5.86 instead of 5.96 :)
To calculate the energy of a photon, you can use the equation:
E = hf
where E represents the energy of the photon, h is the Planck's constant (approximately 6.626 × 10^-34 J·s), and f is the frequency of the light wave.
In this case, you have the frequency of the green light, which is 5.96 × 10^14 s^-1. Now we can substitute the values into the equation:
E = (6.626 × 10^-34 J·s) × (5.96 × 10^14 s^-1)
Multiply the numbers:
E = 3.948496 × 10^-19 J
Rounding to three significant figures, the energy of a photon with a frequency of 5.96 × 10^14 s^-1 is approximately 3.95 × 10^-19 J.
Make sure you double-check your calculations and units to ensure accuracy. If you are still getting the wrong answer, there might be an issue with how the quiz expects the answer to be formatted.
