Electromagnetic Radiation Chart
What kind of light has a frequency of 5.00 × 1016 Hz?
5.00 × 1016 Hz is between 1016 and 1017 Hz, so it is X ray (not UV).
What kind of light has a frequency of 5.00 × 1014 Hz?
It appears to be visible so we will need to find the wavelength to discern the color.
What color corresponds to light with a wavelength of 600 nm? Orange?
Using this chart we can give a definite answer - orange.
What kind of light has a wavelength of 5.00 × 10-8 m?
5.00 × 10-8 m is between 10-8 and 10-7 m, so it is UV (not X ray).
What is a possible frequency for yellow light?
The chart shows yellow as having a wavelength of about 580 nm.
