1. What is the frequency of a light wave that has a wavelength of 5022 nanometers?

2. A circular electric generator coil with 264 loops has a radius of 0.05 meter and is in a uniform magnetic field of 1.25 tesla. If the generator coil is rotated through a quarter of a revolution in 0.015 second, what is the average induced electromotive force?

3. If 26.4 grams of liquid water were completely converted to energy, how many joules would result? Then, if that same number of grams of solid ice were completely converted to energy, would that result in more, fewer, or the same number of joules? Explain your answer.
