What is the wavelength of light (nm) having a frequency of 1.82 x 1014 Hz?

Your school subject is probably physics, not "help on."

Use the wave equation...

frequency*wavelength=c speed of light.
of course the speed of light is 3*10^8 m/s

To find the wavelength of light, you can use the formula:

wavelength (λ) = speed of light (c) / frequency (ν)

where the speed of light (c) is a constant value of approximately 3 x 10^8 meters per second.

To solve for the wavelength (λ), you need to convert the frequency (ν) into hertz (Hz) and substitute the values into the formula.

Given:
Frequency (ν) = 1.82 x 10^14 Hz

First, let's substitute the value of the speed of light (c) and the frequency (ν) into the formula:

wavelength (λ) = (3 x 10^8 m/s) / (1.82 x 10^14 Hz)

To simplify the calculation, let's express the speed of light (c) in nm/s, so we change 3 x 10^8 m/s to 3 x 10^17 nm/s:

wavelength (λ) = (3 x 10^17 nm/s) / (1.82 x 10^14 Hz)

Now, we can divide the numerator by the denominator:

wavelength (λ) ≈ 1648.35 nm

Therefore, the wavelength of light with a frequency of 1.82 x 10^14 Hz is approximately 1648.35 nm.
