1. At the extremes of the visible spectrum we find blue light with a wavelength of approximately 400 nm and red light at 700 nm. What are the frequencies of these radiations? What are the energies of photons at these wavelengths?

2. Calculate the same quantities as in question1 for infra-red radiation with wavelength 100 microns and ultraviolet with wavelength 100nm.
