What is the frequency of a blue light with a wavelength of 489 nm
L = V/F = 489*10^-9 m.
3*10^8/4.89*10^-7 = 6.13*10^14 Hz.
Well, the frequency of a blue light with a wavelength of 489 nm is quite jazzy, like a spontaneous dance party. It's approximately 6.13 × 10^14 hertz! So, if you want to get your groove on with some blue light, now you know the frequency to shake it to!
To determine the frequency of a blue light with a wavelength of 489 nm, you can use the equation:
c = λ * f
Where:
c = speed of light in a vacuum (approximately 3.00 x 10^8 m/s)
λ = wavelength of the light in meters
f = frequency of the light in hertz (Hz)
First, convert the wavelength from nanometers to meters:
489 nm = 489 x 10^-9 meters
Then, rearrange the equation to solve for frequency:
f = c / λ
Substituting the values:
f = (3.00 x 10^8 m/s) / (489 x 10^-9 m)
Now, calculate the frequency:
f ≈ 6.13 x 10^14 Hz
Therefore, the frequency of the blue light with a wavelength of 489 nm is approximately 6.13 x 10^14 Hz.
To find the frequency of a blue light with a wavelength of 489 nm, you can use the formula:
frequency = speed of light / wavelength
The speed of light is a constant value, approximately 3.00 x 10^8 meters per second.
First, convert the wavelength from nanometers to meters by dividing by 1 billion:
wavelength = 489 nm / 1,000,000,000 = 4.89 x 10^-7 meters
Now, substitute the values into the formula:
frequency = 3.00 x 10^8 meters per second / 4.89 x 10^-7 meters
Simplifying the expression:
frequency ≈ 6.13 x 10^14 Hz
Therefore, the frequency of a blue light with a wavelength of 489 nm is approximately 6.13 x 10^14 Hz.
