The James Webb Space Telescope image of Neptune shown above was taken using the NIRCam instrument, which creates images using light with wavelengths between 0.6 and 5 microns. That spans a little bit of yellow and red visible light (0.6 microns to about 0.8 microns) but is mostly "near"
infrared (up to 5 microns).
What is the frequency of light that has a wavelength of 2.80 microns?
Expert Solution

Step 1
Velocity of light is found to be 299792458 m/s that is approximately 3 ×108 m/s.
Velocity of light ( c ) = frequency (v) × wavelength of light (λ)
c = vλ
