The rainbow of visible colors in the electromagnetic spectrum varies continuously from the longest wavelengths (the reddest colors) to the shortest wavelengths (the deepest violet colors) our eyes can detect. Wavelengths near 655 nm are perceived as red. Those near 515 nm are green and those near 475 nm are blue. Calculate the frequency of light (in Hz) with a wavelength of 655 nm, 515 nm, and 475 nm. HINT (a) 655 nm (b) 515 nm (c) 475 nm Hz Hz Hz

a solar panel is a square 0.5m on a side and absorbs all the light that hits it. It the panel has a mass of 3 kg. what intensity of light would be necessary to hold it up against the force of gravity (its own weight)? how much bigger is this than the solar constant (1400 W/m^2)?
Scientists are working on a new technique to kill cancer cells by zapping them with ultrahigh-energy (in the range of 1.00×1012 W) pulses of light that last for an extremely short time (a few nanoseconds). These short pulses scramble the interior of a cell without causing it to explode, as long pulses would do. We can model a typical such cell as a disk 5.00 μm in diameter, with the pulse lasting for 4.00 ns with an average power of 2.00×1012 W. We shall assume that the energy is spread uniformly over the faces of 100 cells for each pulse.
