The wavelength of yellow sodium light is 589 nm. What is its frequency?
1 Hz
distance = speed * time
time = 1/f
so
wavelength = c * 1/f
f = c/wavelength
To determine the frequency of yellow sodium light with a wavelength of 589 nm, you can use the equation:
c = λν
Where:
c is the speed of light (approximately 3 x 10^8 m/s)
λ is the wavelength in meters (589 nm = 589 x 10^-9 m)
ν is the frequency in Hz
Rearranging the equation to solve for frequency:
ν = c / λ
Plugging in the values:
ν = (3 x 10^8 m/s) / (589 x 10^-9 m)
Divide the numerator by the denominator:
ν = 5.092 x 10^14 Hz
Therefore, the frequency of yellow sodium light with a wavelength of 589 nm is approximately 5.092 x 10^14 Hz.
