find the color of light that is known to have an energy of 4.59x10^-19joules
Explanation too please.
E = h*frequency
I don't understand! ! :(
There's nothing to understand. Substitute for h (Planck's constant) and energy from the problem. Solve for frequency in Hz. Planck's constant should be listed in your text or notes. If not you can look on the web.
To find the color of light that is known to have an energy of 4.59x10^-19 joules, we can use the relationship between energy and frequency of light, given by the equation E = hf, where E is the energy, h is Planck's constant (6.62607015 × 10^-34 J·s), and f is the frequency of light.
Rearranging the equation to solve for frequency, we have f = E / h. Plugging in the given energy value of 4.59x10^-19 joules and Planck's constant, we can calculate the frequency of light.
f = (4.59x10^-19 J) / (6.62607015 × 10^-34 J·s) ≈ 6.93x10^14 Hz
To determine the color of light associated with this frequency, we can refer to the electromagnetic spectrum. Visible light falls within a specific range of frequencies, spanning from approximately 4.3x10^14 Hz (violet) to 7.5x10^14 Hz (red).
As the calculated frequency of 6.93x10^14 Hz lies within this range, the corresponding color would be in the violet to blue region of the spectrum.
