the SI Unit of length is meter,which is defined as the lenght equal to 1,650,763.73 wavelengths of light of the light emitted by a particuar energy transition in krypton atoms.calculate the frequency of the light to three significan figures.
c = frequency x wavelength.
Solve for frequency. c = 3E8 m/s
To calculate the frequency of the light emitted by the particular energy transition of krypton atoms, we need to use the formula:
Frequency = Speed of Light / Wavelength
We have the wavelength (1,650,763.73 wavelengths) and we know the speed of light, which is a constant value at approximately 3.00 x 10^8 meters per second.
Let's calculate the frequency:
Frequency = (3.00 x 10^8 m/s) / (1,650,763.73 wavelengths)
Now, we need to convert the wavelength into meters. Since we know that 1 meter is equal to 1,650,763.73 wavelengths, the wavelength in meters is 1 meter.
Frequency = (3.00 x 10^8 m/s) / (1 meter)
Finally, we can solve this equation:
Frequency = 3.00 x 10^8 Hz (or 300,000,000 Hz)
Therefore, the frequency of the light emitted by this particular energy transition in krypton atoms is approximately 300,000,000 Hz (or 3.00 x 10^8 Hz) to three significant figures.
