What is the frequency of radiation whose wavelength is 19.80 ?
thanks:)
To find the frequency of radiation, you can use the formula:
Frequency (f) = Speed of light (c) / Wavelength (λ)
The speed of light is a constant value, which is approximately 3.0 x 10^8 meters per second (m/s).
Given that the wavelength of the radiation is 19.80 units (you did not specify the unit), you can substitute these values into the formula to compute the frequency.
Let's assume that the unit of wavelength is meters:
f = (3.0 x 10^8 m/s) / 19.80 m
Calculating this:
f ≈ 1.52 x 10^7 Hz
Therefore, the frequency of radiation with a wavelength of 19.80 meters is approximately 1.52 x 10^7 Hertz (Hz).
