When you go out into the sun, the UV light can give you a tan. UV light has a frequency of 7.89 x 1014 Hz. What is the wavelength of UV light?
Please use 3 x 108 m/s for the speed of light (c). You will need to upload a file to show how to solve this problem.
Oobleck, I hope you know this site is literally here to give us answers... you’re defeating the whole purpose of it.
i really just need the answer :/
To find the wavelength (λ) of the UV light, you can use the formula:
c = λν
where c is the speed of light and ν is the frequency of the light.
Given that the frequency of the UV light is 7.89 x 10^14 Hz, and the speed of light is 3 x 10^8 m/s, we can rearrange the formula to solve for λ:
λ = c/ν
Substituting the known values:
λ = (3 x 10^8 m/s) / (7.89 x 10^14 Hz)
To solve this calculation, you can use a calculator. Simply divide the value of the speed of light (3 x 10^8 m/s) by the frequency of the UV light (7.89 x 10^14 Hz).
The result will be the wavelength (λ) of the UV light in meters.
this is just like your previous post
v = λf
so plug in your numbers.
sorry. That's just cheating. But surely you can handle
3*10^8 = λ * 7.89 * 10^14
You can be sure that no one will be there to just give you the answer at test time.
